In this article we will look at what types of USB connectors exist and what they are most often used for.

On the left is the connector (male), on the right is the connection connector (female)

1) USB 2.0 Type A

The most common connector for computer connections: keyboards, mice, flash drives and other similar devices.

The connector takes its roots from the 90s, then versions 1.0 or 1.1 had speeds of up to 12 Mbit/s, and USB 2.0, already released in 2000, had speeds of up to 480 Mbit/s, which is still popular today.

2) USB 2.0 Type B

A less common connector, mainly found in large peripheral devices: printers, scanners, multifunction devices, external sound cards and other devices that require more current.

3) USB 2.0 Type Mini-B 4 pin

It was widespread in the mid-2000s, used to transfer data from digital cameras and cameras, but was discontinued due to insufficient power, replaced by a full-length Mini USB

4) USB 2.0 Mini USB

One of the most popular, but already becoming a thing of the past connectors. Often found in phones, MP3 players, digital cameras, portable hard drives and other mobile equipment.

5) USB 3.0 Type A

The new USB type A standard differs in appearance only in color. In modern computers and laptops it is indicated in blue or red. The new format is 10 times faster than its predecessor and has a data transfer rate of up to 5 Gbit/s. One of the main features is its versatility; the connector can be connected to an old USB 2.0, and vice versa.

6) USB 3.0 Type B

The new format is found in a few devices that only require high power, such as large format portable drives, routers, NAS storage, MFPs and other peripheral devices.

7) USB 2.0 Micro USB

The main format for connecting all portable devices: phones, tablets, e-readers and other portable devices.

It was approved as a single charging format for all phones.

8) USB 3.0 Micro USB

The connector differs from its predecessor by an additional 5 contacts and has all the best quality, only with even greater speed. Currently found in portable hard drives and smartphones. The cable has an adaptation with the old connector, that is, the cable from USB 2.0 Micro USB can be connected to a new device.

9) USB Type C

The new format, also known as USB 3.1, is a continuation of the Micro USB standard. The new connector is capable of delivering a throughput of up to 10 Gbps, with the smallest dimensions. It was first used in the new Apple MacBook 12", where this port is universal for all connected devices, including charging. Now this connector is found in all new smartphones and most likely this is not the end.

In our store you can purchase an adapter for your smartphone from a USB 2.0 Micro USB connector to USB Type C so that you can always be connected at first.

In fact, the new USB 3.1 standard and the Type-C connector should calm down the mess and restore order. For everything about everything - one single cable: for data transmission, audio, video signals and power supply. The symmetrical Type-C connector is a real blessing for mobile device users who are tangled in wires. And the USB 3.1 standard allows, for example, to play video from a tablet on a TV while the mobile device is charging.

Just the transition to new specifications poses additional difficulties for manufacturers, which is why sellers and buyers immediately become despondent. The company cannot be blamed for a lack of interest: after the MacBook Pro (2015) entered the market, many manufacturers introduced products that support the new USB 3.1 standard with a Type-C connector, including devices such as motherboards, monitors, external drives and smartphones. Thus, the LG G6 is equipped with a USB Type-C connector, as well as the HTC 10 and Samsung Galaxy S8, which connects to the docking station via a universal connector, turning into a full-fledged personal computer. But a new form does not always mean new functions: for example, Type-C in the Huawei version does not support USB 3.1, and generally uses its own technology for fast charging.

Old devices are a hindrance to new standards

Variety of connectors
Many USB devices still come with one of the old connectors. Type-C should replace them all

Technical breakthroughs always take a very long time if there is a large stock of old technology. Keyboards, mice, external drives, webcams, digital cameras, USB flash drives - millions of these devices still require support for older versions of USB. The problem could be temporarily solved by using universal adapters, but completely new devices with old USB ports are still being released.

And since a regular USB cable cannot easily distinguish between a host and a client device, it still requires two different types of connectors. That's why external hard drives often come with Mini-A connectors, while printers come with typical quad-shaped Type-B connectors. Sooner or later, USB Type-C should replace not only these connectors - using a cable it would be possible, for example, to connect peripheral devices to a PC without any problems. Moreover, Type-C can send DisplayPort, HDMI and even TRS jacks into oblivion.

Don't be confused: Type-C is not USB 3.1

"Talking" logos
Logos should reflect what functionality the USB connector provides. Unfortunately, not all manufacturers use them

Since the USB consortium approved two other specifications at the same time as the Type-C connector, there is often some confusion in the concepts. Firstly, we have a new Type-C connector with a mirror arrangement of 2x12 pins, making the port insensitive to the orientation of the plug - which means that the problem of “how to plug in a USB Type-A plug the first time” will be available very soon forget.
Secondly, along with the new connector, a new USB 3.1 standard has been introduced, increasing the data transfer rate ceiling to 10 Gbps (gross).

Further, USB Power Delivery (USB-PD) is presented in a new, second revision: it implies faster charging of connected devices by increasing power (20 V, 5 A instead of the previous 5 V, 0.9 A). In other words, although USB Type-C, USB 3.1 and USB Power Delivery are often equated, they are not equivalent terms or synonyms. So, there is, for example, a USB 2.0 interface in Type-C format or a USB 3.1 port without support for Power Delivery fast charging.

But that is not all. The consortium cannot be completely blamed for the mess, since it has moved away from using the usual nomenclature: with the advent of USB 3.1, USB 3.0 ceased to exist in the sense that this previous version is now classified as USB 3.1 Gen 1, and the newly introduced technology is called USB 3.1 Gen 2. But many USB cables and devices are sold under the name USB 3.1 - without specifying which generation they are referring to.

The USB Consortium, however, has developed a system of logos to designate USB Type-C connectors so that you can distinguish, for example, a Type-C plug supporting USB 3.1 Gen 1 from a plug supporting USB 3.1 Gen 2 or even the old USB 2.0, but for starters logos need to be examined carefully. It's not uncommon to have to look at the manual to figure out which version you're using—assuming detailed documentation is available, of course. It's not surprising that many manufacturers continue to use the previous name USB 3.0.

Limit values ​​of USB versions
USB 3.1 Gen 2 doubles data transfer speeds and increases current for fast charging

To all this diversity should be added the Thunderbolt 3 interface, developed primarily by Intel and Apple. Thunderbolt from the third version also uses a Type-C connector, but is not entirely compatible with USB 3.1. With active Thunderbolt 3 cables, throughput reaches up to 40 Gbps (gross)—four times that of USB 3.1. This not only provides very high data transfer speeds, but will also allow you to transfer multiple video streams with 4K content over DisplayPort and even use external graphics cards. Complex technologies require the use of active electronics in cables. USB devices can be connected to the Thunderbolt 3 port, but never vice versa.

Difficult choice of cables

The confusion doesn't stop with standards and versions alone. If previously it was possible to limit the choice to one USB cable with the required types of connectors, with USB 3.1 and Type-C it will not be so easy. Here, as in the case of standards and versions, there is currently a huge lack of information: not all Type-C cables can transmit data, video and supply power. In many cases, it is not clear to users whether a Type-C cable supports Power Delivery fast charging or an alternative mode for video transmission, because logos and markings, as a rule, are simply not there.

Premium motherboards
Currently, USB 3.1 Gen 2 is supported only by select premium motherboards. Among them is Asus Rampage V 10, equipped with two Type-A and two Type-C ports, it costs about 38,500 rubles

It is often impossible to determine whether a cable supports USB 3.1 or just USB 2.0. On the Amazon website, there are very often reviews from upset customers who, after purchasing, discovered that the purchased cable does not support the fast charging technology of their smartphones. Even the designation by some manufacturers, for example, Aukey, of a USB 3.1 Gen 1 cable with Type-C and Type-A ends as a “Type-C to USB 3.0 cable” does not help to get out of this difficult situation at all - this is completely wrong.

If you decide to get a device with a Type-C connector, be sure to make sure that the package includes a cable - only then will all your requirements be satisfied. Computer hardware supplier Hama, for example, offers several Type-C cables with detailed specifications, but prices start at 1,000 rubles. Buying a Thunderbolt 3 cable will cost even more - you will need to shell out about 2,000 rubles. But all the functions are provided here. If this price is too high, then willy-nilly you will have to rummage through product descriptions and customer reviews about them in search of the right cable.

USB-C: balanced plug

Data transfer, power supply and dialogue between devices - each of the 24 pins of the Type-C plug performs a separate function. It is easy to notice that their arrangement is symmetrical.

Displays, laptops and adapters

To transfer video in one of the alternative modes (DisplayPort or HDMI), that is, for example, from a laptop to a monitor, you should also pay attention to the technical requirements. There are currently several monitors on the market with a USB Type-C connector from LG, Eizo, Acer and HP (for example, Envy 27, about 40,000 rubles). For video output, the DisplayPort standard is almost universally used, which indeed works quite reliably. But if we talk about fast charging, which places special demands on the monitor’s power supply, then in many cases buyers have questions.

Alt mode video
The USB-C connector, for example, like that of the LG 27UD88 (about 38,000 rubles), usually provides reliable video transmission to the monitor, but it does not always provide fast charging with Power Delivery

However, supplying power from the monitor to the laptop is not always necessary. The Asus MB169C+ portable 15-inch monitor (about 15,000 rubles) receives power from the laptop via a fully used Type-C connector.
One way or another, nowadays it more often happens that a laptop with a USB Type-C connector is connected to a monitor via an HDMI or DisplayPort port. In such cases, an adapter is required that converts the video signal and transmits it to the monitor using the desired standard. Such accessories can be purchased from about 1000 rubles. Compared to other cables, choosing adapters is quite simple, because their task is only to convert the video signal without taking into account other features of USB 3.1.

For those interested in a laptop or tablet with a Type-C connector, the choice is currently limited, but great. In addition to the MacBook (12 inches), there are hybrids Acer Aspire Switch 10 V (about 25,000 rubles) and Asus T100HA (about 18,000 rubles). And the young Google Pixel Chromebook is equipped with two whole Type-C ports (though only of the USB 3.1 Gen 1 standard), but it has not yet gone on official sale in Russia.

Old documentation
Even though the Acer Aspire Switch 10 V only has one Type-C port, the manual lists older types of USB connectors

Probably, it is unlikely that any user will dare to transfer all their peripheral devices to Type-C at once, so most laptop owners will first need a USB 3.1 adapter to transfer data and video signals via a USB Type-A, HDMI or DisplayPort cable. Prices for recommended flexible models start at 2,500 rubles, such as the Icy Box IB-DK4031. Club 3D SenseVision is more expensive - about 6,500 rubles - but it includes HDMI, DVI, USB 3.0 Type-A, 4 USB 2.0 connectors, USB fast charging, as well as jacks for connecting a microphone and headphones.

The choice for desktops is less rich at the moment: traditionally, motherboard manufacturers introduce new standards in premium models. The only motherboard with four USB 3.1 Gen 2 ports (two each Type-A and Type-C) is the Asus Rampage V 10, which costs about 38,500 rubles. At least the indication of fast transfer of 10 Gbit/s is also on the panel of interface connectors. One of the USB 3.1 options from the lower price category of desktops is the MSI X99A SLI (LGA 2011-3) with one Type-A and one Type-C port for about 15,000 rubles.

Universal adapter

Switching to computers with a Type-C connector will require an adapter with different types of ports for the peripherals.

> Club 3D SenseVision (about 6500 rubles)
The adapter is relatively expensive, but is equipped with a large number of ports, including HDMI, DVI, microphone and headphone jacks, as well as four USB 2.0 ports and a fast charging connector (USB 3.1 Gen 1)

> Icy Box IB-DK4031 (about 2500 rubles)
A simpler version of the adapter with a Type-A connector (USB 3.1 Gen 1), HDMI,
as well as a Type-C connector with Power Delivery for fast charging of external devices.

Benefit from external storage thanks to USB 3.1

Fast memory
USB 3.1 Gen 2 gives many external SSDs, such as the Freecom mSSD MAXX, a significant jump in speed

Of course, network storage with a RAID configuration and external drives, primarily flash memory - solid-state drives and USB flash drives, benefit from the high data transfer speeds of USB 3.1 Gen 2. But for the latter, the availability of USB 3.1 Gen 2 is currently reduced to zero. The offered flash drives from SanDisk, Kingston and Corsair, positioned as USB 3.1, transfer data at a speed of no more than 5 Gbit/s, that is, they belong to the first generation. However, for most flash drives this should be sufficient for now.

As for external solid-state drives, the manufacturers Freecom (mSSD MAXX, about 8,000 rubles) and Adata (SE730, about 9,500 rubles) offer drives with USB 3.1 of the second generation. The first practical tests show that the high-speed interface does indeed provide significantly higher data transfer rates. Terramaster offers a two-bay D2-310 network storage enclosure (about 10,000 rubles) with support for USB 3.1 Gen 2, which should also make a good impression on high-speed SATA drives in a RAID array.

Music over USB-C
The score has been opened for the headphone jack on a smartphone: a Type-C to TRS adapter will soon appear as standard

It should be separately noted that memory manufacturers do the best job of specifying versions and standards and are the least likely to leave their customers halfway. The remaining manufacturers must urgently supplement the documentation and properly implement the standards.

Transitioning from one generation of technology to the next has always been a long and often confusing process, but not since the days of VHS and Betamax has there been such confusion as now. Someday, the USB 3.1 / Type-C configuration will really make life easier for everyone - especially users, but for now there are many difficulties to be overcome.

USB - what is it? Types and photos

What is USB? Today, probably only the lazy do not know or have heard about this. USB has firmly entered the life of modern people, and many areas of activity cannot be imagined without it. USB has surpassed all other similar interfaces in popularity that interact with computer peripherals. Almost all electronic gadgets and systems are equipped with USB connectors: computers, phones, tablets, TVs, car radios and many other devices.

USB concept

A technical definition will help you understand what USB is. The official documentation states: USB, Universal Serial Bus - universal serial bus. In essence, it is a software tool that makes connections for transmitting data between electronic gadgets.

USB has its own symbolic icon in the form of geometric shapes: two circles (small and large), a triangle and a square. Three branched lines emerge from the large circle, at the ends of which are the remaining figures.

You can define what USB is in a simpler concept. This is the connector to which a device with a plug of the same standard is connected. For example, using USB, a keyboard, mouse, and printers are connected to a personal computer. Phones, smartphones, tablets, e-readers, portable hard drives and many other gadgets are connected to exchange information, install various updates, and settings.

Features and Benefits

This interface was developed and introduced at the end of 1994. Companies such as Microsoft, Intel, Philips and US Robotics had a hand in the emergence of USB.

Previously, external third-party devices communicated with the PC through such switching means as PS/2, serial and parallel input ports, a separate connector for connecting game controllers, and no one had even heard of what USB was. When developing new gadgets, there was an urgent need to unify switching capabilities. The presentation of the new standard led to increased functionality of the computer and stimulated the development of third-party products with the USB bus.

Today, all PCs and laptops are required to have USB connectors. Up to 12 USB connectors can be mounted on a desktop computer; a laptop has 3-4 inputs. Any modern “self-respecting” gadget has a USB port.

Simplicity and ease of use have become synonymous with USB technology. It allowed interaction with the “Plug and Play” specification, which assumed reliable, fast and user-friendly switching of external sources.

USB standardization

Trial specification standards were presented at the end of 1994. Several more versions were released throughout the year, and on January 15, 1996, the USB 1.0 standard was presented. It was characterized by two types of data exchange: a high throughput channel of up to 12 Mbit/s and a low throughput channel of 1.5 Mbit/s. With high throughput, the length of the USB cable was 3 m, and with low throughput - 5 m. The voltage for connected devices was determined to be 5 V with a maximum current of 500 mA. Up to 127 gadgets could be connected. Moreover, they could all function with different access standards.

In September 1998, work was carried out on the detected errors, the speed was increased to 15 Mbit/s, and USB version 1.1 was launched.

The beginning of 2000 was marked by the release of the USB generation 2.0 interface. A high-speed data processing and transmission mode was introduced. USB 2.0 received three types of bandwidth:

from 10 to 1500 Kbps was used for operation with keyboards, mice and gaming gadgets; from 0.5 to 12 Mbit/s reserved various video and audio media; from 25 to 480 Mbit/s worked with hard drives (HDD) and video stream processing.

Additional Specifications

In 2005, USB Wireless technology was developed. A characteristic feature was stated to be wireless switching with high data transfer rates. Within a radius of 3 meters the speed was about 480 Mbit/s, 10 m – 110 Mbit/s.

Through the joint efforts of Microsoft, Intel, Hewlett-Packard and some others, the USB 3.0 specification standard appeared. This version is fully compatible with 2.0. The connectors of the latest specification have a characteristic blue plastic color, unlike the white of the previous version. Specification 3.0 has an additional four switching lines, making the cable slightly thicker and the throughput increased to a stratospheric 5 Gbps. With these parameters, for example, information with a volume of 1 TB can be transferred in approximately 50 minutes. Whereas with standard 2.0 the same volume is transmitted in about 9 hours.

The latest version of USB has a higher current of 900 mA. This parameter made it possible to connect a larger number of devices to the connector compared to 2.0.

There is also a USB OTG specification that allows connected devices to unilaterally determine when to be a host and when to be a peripheral.

USB connectors

The USB specification has two types of connectors/plugs: type A and type B.

Type A connects a third-party USB device and a computer. It is on the controller side. When you connect any USB gadget, the operating system itself instantly finds the driver. If there are none, the device is always equipped with a software disk, which includes the necessary installation element.

Type B is present on the USB peripheral side. These are mainly scanners, printers or multifunction devices. Both types include several plug/connector configuration options: mini USB and micro USB.

The mini USB connector/plug is more compact in size and is found on early versions of smartphones, cameras, camcorders, e-books, etc.

The micro USB connector/plug is even smaller in size than the previous version. It is often found in modern smartphones.

Disadvantages of the USB interface

Due to design features, mini USB and micro USB connectors often fail before their service life. This is due to the fact that such connectors are usually found in gadgets that very often have to be connected to a computer or charged (phones, smartphones, PDAs, MP3 players). It is worth noting that USB technology not only allows you to exchange data, but also makes it possible to charge devices through its connection.

The stated throughput of the 2.0 specification of 480 Mbps is not true. This happens because data is transmitted in both directions over a single twisted pair cable. To achieve maximum speed, 2 clock cycles are required when exchanging information, which, by the way, is implemented in USB 3.0.

USB (Universal Side Bus) is a universal serial bus that is used to connect a variety of digital devices to a computer. Now used to connect almost all peripheral devices, for example, scanners, manipulators, etc.

The USB bus appeared in 1995 and since then has gained enormous popularity and become truly universal. The advent of the USB bus made it possible to replace such obsolete interfaces as PS/2, serial port and parallel port. At the moment, these interfaces are used very rarely.

History of development

Since 1995, the USB bus has received 3 major updates. Version USB 1.0 came out in early 1996 and could transfer data at speeds of up to 12 Mbit/s, and the maximum cable length was 5 m. Version USB 2.0 came out in the spring of 2000 and received a maximum data transfer speed of 480 Mbit/s. This version of the USB bus is now used everywhere. The last USB bus update, number 3.0, was released in 2008. The data transfer rate in this version was 5 Gbit/s. Currently, USB 3.0 is being actively implemented by computer manufacturers and is gaining popularity.

The newest version of the USB 3.0 bus has many innovations compared to USB 2.0. To increase the data transfer speed, we had to add 4 more conductors. Because of this, the USB 3.0 cable has become significantly thicker. The contacts of the new conductors are located in the connector in a separate contact row. The current was also increased from 500 mA to 900 mA. This allows you to supply power to more powerful devices. A distinctive feature of USB 3.0 is the blue connectors. This allows you to accurately distinguish the USB ports of the new version.

What is USB: USB Type A and USB Type B

One of the features of USB is the different types of connectors. The first version of USB provided two types of connectors: USB Type A and USB Type B. The USB Type A connector type is intended for installation on the controller side, that is, for installation in a computer. The USB Type B connector is used for installation into a connected device.

Later, connectors for connecting devices with small dimensions appeared: Mini-USB and Micro-USB. These connectors are used in MP3 players and other mobile gadgets.

Micro USB connector pinout— the technological process does not stand still. Modern models of various digital devices are strikingly different from their older counterparts. Not only their appearance and internal equipment have changed, but also the methods of connecting to computers and chargers. If only 5-7 years ago many phones and even cameras did not have this capability. But at the moment, absolutely every digital device can be connected to a personal computer or laptop. Phone, player, smartphone, tablet, video camera, player or camera - they are all equipped with connectors that allow you to connect them to other devices.

Micro USB connectors. Types of USB connectors, their features

But, as you can easily see, the connector is different. And for some reason the cord purchased with the phone cannot be used with your favorite player. As a result, a bunch of cables accumulate, you constantly get confused in them and cannot understand why it was impossible to make one wire suitable for connecting all devices. But, as we know, this does not happen. Although now there is a more or less standard connector, at least for smartphones, phones and tablets. And its name is micro-USB. What is this miracle and how does it work, how is it done micro usb connector pinout, we will tell you below.

Micro USB connector: what is it?

The two most popular connectors lately are mini and micro-USB. Their names speak for themselves. These are smaller, more practical designs that are used on smaller digital devices to save space and perhaps create a sleeker appearance. For example, a micro-USB connector for a tablet is almost 4 times smaller than a standard USB 2.0, and considering that the device itself is several times smaller than a personal computer or even a laptop, this option is simply ideal. But there are also some nuances here.

For example, more can never be made into less, so micro-USB connectors cannot even be replaced with mini-USB. Although in some cases the reverse process is acceptable. And replacing a micro-USB with your own hands is unlikely to end in anything good. This is such a fine job, and besides, you need to know exactly how it’s done. micro usb connector pinout. In addition, the word “micro” covers several types of connectors, and you need to remember this. Especially if you are trying to buy a new wire. Your tablet's micro USB may not be compatible with the connector on the end of the cable you purchased.

Varieties

Micro-USB connectors can be of two completely different types. They have different areas of application and, accordingly, they look different. The first type is called micro-USB 2.0. type B - it is used in devices by default and is an unspoken standard for the latest models of smartphones and tablets, because of this it is very common and almost every person at home has at least one micro-USB 2.0 cable. type B.

The second type is micro-USB 3.0 - these connectors are not installed on tablets, but can be found on smartphones and phones of some brands. Most often they are used to equip external hard drives.

Advantages

The main advantages of micro-USB connectors for tablets include increased density and reliability of the plug. But this fact does not exclude the possibility of problems with these particular components, especially with inept attempts to make repairs and pinout the micro USB connector. Most often, the cause of breakdown is the carelessness of the owners of digital devices themselves. Sudden movements, tablets and phones falling onto the floor or even asphalt, especially on the side where the connector itself is located, attempts to correct something with your own hands without the appropriate knowledge - these are the main reasons why even the most durable parts of USB ports fail out of service. But it happens that this happens due to wear and tear of the device, improper operation or manufacturing defects.

Most often, the cause of malfunction is either the micro-USB connectors themselves, or the parts adjacent to them and connected to them in a circuit. For any experienced craftsman, replacing it is a matter of minutes, but not everyone can do it at home. If you are still interested in how you can repair the micro-USB connector yourself and how it is done micro usb connector pinout(or, in other words, desoldering). Then you need to understand that this process, although not the longest and most difficult, if you approach it wisely and preliminary reading of the relevant information. Some tips will be given below.

Micro USB connector: micro usb connector pinout

As you know, with ordinary ports and connectors everything is simple - you just need to take an image of the front part of their connector, but in a mirror image, and solder it. With USB mini- and micro-types everything is a little different. Their connectors contain 5 contacts, but on connectors of type B, contact number 4 is not used, and on type A it is closed to GND, which occupies the fifth place.

Functions of the “legs” of the micro-USB connector

Since most modern tablets have micro-USB, which serves not only for charging, but also for synchronization, problems with it arise more often due to the more frequent use of the connector.

So, as mentioned above, a regular micro-USB connector has five “legs”. One is positive, at five volts, and one is negative. They are located on different sides of the connector and, accordingly, suffer less when separated from the motherboard. Only one “leg” of the connector, which more often than others is pulled out of the contact pad, is subject to more wear. It is located closer to the minus “leg”. If this contact is damaged, the device cannot be charged. That is, the system can see the power supply, but the charging process will not occur.

The remaining two “legs” are responsible for synchronization, that is, for the ability to upload and download photos, music, etc. They do this at the same time, so the separation of one will entail the cessation of the work of the second.

Knowing the functions of the “legs”, you will be able to determine which contacts are causing you to have problems and which of them you will need to solder to get your tablet back into operation.

Incorrect pinout of the micro USB connector or incorrect replacement of it - consequences

Having soldered micro-USB incorrectly, owners most often encounter the following problems:

1. Short circuits of the power supply if they soldered the inverted type.
2. The tablet detects the charging cord, but the battery (battery) does not charge.
3. The tablet's battery charges perfectly, but it does not sync with a laptop or computer.
4. The tablet works fine, but sometimes it “reminds” you that you should take it to a workshop instead of soldering it yourself (for example, charging does not start immediately after turning it on, or sometimes the cord needs to be pulled out and reinserted several times before charging starts).

The Future of Micro USB

Since these are some of the most popular ports today, if you learn how to change them once and learn how to do it micro usb connector pinout, this skill will help you out very often in the future. And let them not be accepted as the “gold standard” in the development of phones and other digital devices. And we still have to have a whole collection of wires specifically for an Acer laptop, for a Samsung phone, for an Apple iPad and a Nikon camera, but the active use of micro-connectors gives us hope that soon instead of a “bouquet” we will have one on our shelf micro-USB cable suitable for at least 90% of the equipment in the house.

What types of USB connectors and plugs are there?

Mini USB on the left, Micro USB on the right.
Mini USB is much thicker, which makes it impossible to use
it in compact thin devices.
Micro USB is easy to recognize by its two notches,
holding the plug firmly when connecting.

Three brothers of the same family.
Mini USB and Micro USB are much thinner than usual.
On the other hand, the “crumbs” lose
in the reliability of an older comrade.
