Topboard USB 2.0 cable in colors. Pointing cable yusb. USB specifications

Connected by universal serial bus. Therefore, the USB pinout on the motherboard plays a very important role in the modern computer. There are two ways to install such connectors. The first is the installation directly on the board. At the same time, it is displayed on the back side and is immediately ready for work. But it is not always convenient to connect to it - and therefore developed another method. Its essence lies in the prepared sector on the main board of the PC, to which the wires from the front panel are joined. And on it and there is a connector.

In one universal uSB standard 2.0 enters 4 contacts. The first of them is indicated by "+ 5V". With it, the power supply is provided to the peripheral device. The second and third are the contacts for which information is transmitted. They are indicated by "Data-" (minus data transfer) and "Data +" (plus the last, 4th, which enters the motherboard, is "GND" - the supply of land. In accordance with the standards taken today, they are indicated by the following Flowers: Nutrition - Red, "Data-" - white, "Data +" - green, and "GND" - black.

Such interface connections are made in pairs, therefore on the board on one contact group 2 USB standard connector is immediately located. The flipping consists of 9 contacts: 4 - per connector, 4 - to another, and the last two play the role of the so-called key. In one place there is a pin, and in the other it is not. So done so that it is impossible to confuse them and to correctly perform the connection. The fitting from the front panel is also performed in the same way. Therefore, when connecting the first to the second must be established without problems. If this does not happen, then you need to see if you are doing everything right.

IN lately The 3rd version of the USB Standard is becoming increasingly popular. The pinout on the motherboard is significantly different because much more wires are used to transfer information. They are in this performance of only 9. In addition to the previous 4, 2 pairs of "SuperSpeed" + and 2 pairs of the same species are added, but only with a minus, as well as "GND Drain" - additional land. Exactly large quantity Wires and allows you to increase the wires of them in color accordingly, blue, purple - minus, yellow, orange - plus, and another black - additional grounding. As the number of wires is increasing, the USB pinout on the motherboard is increasing directly proportional. For such a standard, 19 contacts are already used. One of them is the key, and its purpose is to ensure the correctness of the connection.

Using a universal serial bus connected to modern computers and laptops great many various devices. Printer, scanner, MFP, flash drives, keyboard, mouse and other devices that are significantly expanding the PC capabilities - all this connects with the computer that is exactly the interface. It is not always convenient to connect to the back of the computer, and the number of integrated connectors may not be enough. It is to solve such a problem and a USB pinout on a motherboard, which allows you to significantly increase the number of ports.

UBS connectors are the most common types of connector, which are used to connect different types of digital electronic devices.

We are sure - each in the house has many cables with such connectors, because they are used to connect peripheral devices to a computer: mouse, joysticks, printers, scanners, external hard drives and more.

In contact with

Also when buying a mobile phone, you get connections with it to connect the gadget to the computer and the charger.

The concept of pinout

Sometimes it happens that due to the breakdown of the connector or the cable break stops working charger device for phone Or something connected to the computer. This is for a person who does not own the skill to work as a soldering iron, - an unpleasant surprise And the problem.

But, for a person familiar with the fundamentals of electronics and able to solder, the task is solved simply - a new connector is soldered or the old one turns out, and our favorite devices function again.

However, before reinforcing repair, you need to know topboard USB Connector - The location of the colors in relation to the contacts of the connector. Incorrect decay will lead to the failure of the connected gadgets.

USB Overview Connectors

USB (universal sequential tire) - The data transfer standard, which was developed in 1994 to organize an interface between a computer and peripheral devices.

Now it is used both for transmitting data between digital devices, and to charge the passive device batteries from the active, so-called "host". An example is the charging of the phone from the computer.

Connectors are divided into three types:

First type - USB 1.1

Was designed one of the first to expand functionality Computer and made it possible to connect additional devices to a computer, including mobile phones for transmitting speech digital form.

Due to the fact that the data transfer rate was low, USB 2.0 came to shift. Currently, USB 1.1 is considered obsolete and practically does not apply.

Second Type - USB 2.0

The most common at the moment and is widely used. Most electronic devices sold in electronics stores have USB 2.0 connectors, despite the fact that they are no longer quite satisfying the latest transmission rate requirements. In particular, the hard drives can read information at a speed of 3-4 times greater than the speed provided by this type of devices. However, they remain common due to the fact that for the operation of mice, keyboards and other devices, this speed is quite suitable.

Third Type - USB 3.0

It is a new generation of devices, whose transmission rate satisfies the most high-speed hard drive and provides a speed reserve for the future. Connectors this type Specially designated in blue.

All Connectors considered types have constructive differenceswhich can be determined by designation:

Letters F and M in USB marking Connectors mean:

• F (Female) - a slot connector (mother);
• M (MALE) - plug connector (dad).

For connecting to portable and mobile devices, mini - USB are developed, and later - Micro - USB.

MINI-AB and Micro-AB connectors are used as transitiones for MINI A and MINI B, Micro-A and Micro-B, Micro-A and Micro-in each other.

Pinout connector

Spacking USB 2.0 connector is:

• Red wire Shipping to contact 1 connector: Food is served + 5V;
• White wire - to contact 2: information (D -);
• Green wire - to contact 3: information (D +);
• Black wire - To contact 4: Common.

Mini and micro USB cables have five wires of different colors and a five-pin connector. The difference of the splitting of such micro connections from the splitting of USB 2.0 connectors lies in the following:

• the decay of the first three contacts is similar to USB 2.0;
• the lilac wire goes to contact 4 - this is id; In connectors A - not used, in connectors B - connected with the case;
• black wire goes to contact 5 - common.

Spacking USB 3.0 connectors It is made as follows:

• the decay of the first 4-contacts is identical to the disintegration of USB 2.0 connector;
• blue wire comes up to contact 5 - transmission of information with a plus sign;
• yellow wire - to contact 6 - transfer information with a minus sign;
• additional case - to contact 7;
• purple wire - to contact 8 - transmission of information with a minus sign;
• orange wire - to contact 9 - transmission of information with a plus sign.

Micro and mini USB for mobile phones

All modern mobile phones are charged through mini and microconnectors from own charger. The plot of mini and microconnectors were considered above.

Now let's talk about why it happens that it seems that the charger in its parameters (voltage and charging current) is suitable, and the connector from your phone is good for it, but the charger is not "native" - \u200b\u200band the charging does not go. Why?

The case is in some differences of the plot of mini and micro-indoor phones inserted into the charger.

For example, such gadgets like HTC, Philips, Samsung, as well as Nokia and LG recognize the charger for their own if 2 and 3 contact in the connector is shortened. By connecting these contacts in the AF connector of the charging device, you can easily use it to charge these types of phones.

Motorola devices "will require" the resistor installations, with a rating of 200 kilomes between 4 and 5 contacts. Without him the device is charging very slowly.

Summarizing the said, you can make a conclusion that when repairing cables to your favorite gadgets, it is important to know the pinout connectors to properly cover the cable wires, and then your electronic "friends" will serve you for a long time.

USB (Universal Serial Bus - Universal Serial Tire) All variety of USB versions 2.0 is reflected in the picture below. Picture clickable.

In order to avoid discrepancies: in all tables, the type of connector is given from its external, the working side (and not from the mounting side!), If the opposite is not specifically stipulated. The insulating details of the connector are marked with light gray, metal parts are dark gray, and the cavities of the connector are indicated by white.

Well, and simplified, so to speak practical scheme:

The name of this or that connector is supplied with letterpress indexes.

Connector type:

• A - active, nourishing device (computer, host)
• B - Passive, Connected Device (Printer, Scanner)

Floor Connector:

• M (MALE) - Plug, "Dad"
• F (Female) - nest, "Mom"

Connector size:

For example: USB Micro-BM-plug (M) for connecting to a passive device (B); Micro size.

Pointing USB connector (sockets and plugs)

Purpose of wires in USB cable such:

1. Red VBUS (+ 5V, VCC - Voltage Collector Collector) +5 Volt constant voltage Regarding GND. Maximum current - 500 MA
2. White D- (-DATA)
3. Green D + (+ Data)
4. Black GND - Common Wire, Earth, Minus, 0 Volt

MINI and Micro connectors contain 5 contacts:

1. Red VBus
2. White D-
3. Green D +.
4. ID - in the connectors "b" is not involved; In the "A" connectors, closed with GND to support the OTG function
5. Black GND.

Among other things, the cable contains (though, not always) the shield cable wire is the case, screen, butter. This wire is not assigned to this wire.

Good news

In the Internet, a reversive (revorsible) plug Micro-USB, which is similar to USB 3.1 Type-C does not require a clear orientation of ± 180 ° when connecting to the jack.

How to reconstruct usb?

Well, with the usual USB everything is simple - take the image of the front of the connector in the mirror image and solder.

MINI USB and USB Micro plugs with a filling side are shown in the picture below. If you solder a simple data cable (for PC connection and mobile phone / smartphone / tablet), then the 4th contact is not using. When soldering the OTG cable (to connect to the smartphone of flash drives and other things), the 4th contact is connected from the 5th.

MINI and Micro connectors contain 5 contacts. In connectors like "B" the fourth contact is not used. In connectors like "A", the fourth contact is closed with GND. And the most contact GND gets the honorable fifth place.

Pointing USB ports, micro YUSB breakout, mini charging connector

Currently, all mobile devices and desktop electrical devices have in their arsenal ports for data transmission. Modern gadgets can not only exchange information via USB or Micro-USB, but also carry out batteries. In order to spend the competent pinout of the contacts, first you need to study the circuits and colors of the wires of wires.

Wire colors in USB cable

Connector Scheme for USB 2.0

In the diagram you can see several connectors, differing from each other by a specific sign. For example, an active (feed) device is denoted by the letter A, and the passive (connected) device - the letter V. To the active includes computers and hosts, and passive make up printers, scanners and other devices. It is also accepted to separate the connectors on the floor: M (Male) or "Dad" is a plug, and F (Female) or "Mom" is the connector socket. There are formats: mini, micro and without labeling. For example, if the designation "USB Micro-Vm" meets, this means that the plug is designed to connect to a passive device according to the Micro format.

To pinp the nests and plugs, you will need knowledge about destination of wires in a USB cable:

1. the red VBUS ("plus") passes a constant voltage of 5 volts relative to GND. Minimum power electric current For him, equal to 500 mA;
2. the white wire is connected to "minus" (D-);
3. the green wire is attached to the "plus" (D +);
4. the black color of the wire means that the voltage in it is 0 volt, it carries a minus charge and is used for grounding.

In Mini and Micro formats, connectors contain five contacts: red, black, white and green wires, as well as id (which in the connectors of type A is closed on GND, and in the connections B is not involved at all).

Sometimes a bare wire Shield can be found in the USB cable. This wire does not have the numbers.

If you use the table in the work, the connector in it is shown from the external (working) side. Light gray color have insulating connector parts, dark gray in metal parts, and cavities are indicated by white.

In order to carry out the correct USB splice, you need to mirror the image of the front of the connector.

Connectors from mini and micro formats on USB consist of five contacts. Therefore, the fourth contact in the type connections in the work does not have to use. This contact in the type A connectors is closed with GND, and for the GND itself, the fifth.

As a result, non-cunning manipulations can be independently making a pinout for ports. USB Miscellaneous format.

USB sprinkling version 3.0 is characterized by adding four non-ferrous wires and additional grounding. Thereby uSB cable 3.0 is noticeably thicker than your younger fellow.

Plotting USB Connector: Normal, Mini, Micro

In our age computer technology, smartphones and gadgets are difficult to find such a person who would not know what the USB connectors are. Also, almost everyone understands words as mini and micro-usb connector. After all, such things we use almost daily, which naturally. Similar connectors are on chargerand on all computer peripheral devices.

But what to do if the sprinkling moved from the base, and there is no possibility to even understand what color and what kind of contact was soldered? Here you already need to apply knowledge, and what, now we will try to figure it out.

Spacking like plug, or, in other words, pinout USB wiresIn essence, nothing superpose does not bother. Having understood with the sequence and flowers of anyone who can keep a soldering iron in his hands, can cope with such work.

But first, it is necessary to understand what is a USB plug.

Types of USB plugs

What is a USB connector?

In essence, this is a connector with a variety of features, ranging from USB power to the transfer of complex information data. Such a cable replaced the previously used compound options with a computer (PS / 2 ports, etc.). It is used to date for all devices connected to a personal computer, whether mouse, flash drives, printer, camera or modem, joystick or keyboard - USB cables have become truly versatile.

There are three types of similar connectors:

• 1.1 - Its purpose - outdated peripheral devices with the possibility of transmitting information only to one and a half megabita per second. Of course, after a small refinement by the manufacturer, the transfer rate rose to 12 Mbps, but with higher-speed options, he could not stand competition. It would still be when Apple has already had a connector supporting 400 Mbps. Now such species are also there, but there are very few of them, since they have long appeared fast USB wires, mini usb, and in general, uSB speed In a person's life occupies a special place. Everyone is rushing somewhere, hurry to live, there are people who practically do not sleep, but because the information is downloaded, the more preferable the connector, isn't it?
• 2.0. At the end of the last century, the second generation of such connectors was published. Here the manufacturer has tried - the transfer rate has grown almost to 500 Mbps. And he was intended mainly for complicated gadgets, such as a digital video camera.
• 3.0 - this is already really high tech. The maximum data transfer rate of 5 Gbps provided this USB connector demand, which practically reduced the first and second version on zero. In the third series increased the number of wires up to nine against four. However, the connector itself is not modified, and therefore it can still use the types of first and second episodes.

Designations during pickling

Considering the circuit of the pinout, it is necessary to understand all the symbols that are present on it. Usually indicated:

USB pinout options

• The view of the connector - it can be active (s) and passive (B). Passive call the connection of the printer, scanner, etc. In general, the connector that works only on adopting information. Through active data and data transfer.
• The shape of the connector is "Mom", that is, the nest (F), and "dad" - plug (M).
• Connector size - Normal, Mini and Micro.

For example, USB AM, that is, the active USB plug.

Place the wires in colors should be as follows (from left to right):

• Red wire - plus, constant voltage in 5V. With a maximum current of 500 milliam.
• White Wire - Data-
• Green Wire - Data +
• The wire of black - this wire is common, "earth", "minus". There is no voltage on it.

But Mini and Micro connector include 5 wires with this location:

• Wires of red, white and green colors - are located similarly to the first option.
• ID - This wire in the "B" connector is free. In "A" it needs to be closed on the wire of black.

Sprinkage of contacts in "Mom" USB 3.0

Sometimes there may be a separate wire without insulation in the connector - this is the so-called "mass" that soldes to the body.

According to the schemes presented - the outer side is visible here. In order to independently solder the plug you need to take mirror reflection Figure, and how probably it became clear, the microusb-pinout is not at all more difficult than the usual USB connectors.

By the way, if the spoiled parts of the cable are supposed to be used only for charging mobile, it will be more convenient, looking at the colors of the wires, just black and red. Such a connector is quite enough for the phone, it will charge it. What to do with the rest of the wires? They do not need to produce any action.

Disincorder USB connector. Wardrocking scheme:

The splitting of the USB connector was developed since 1994, while the development team consisted of engineers from advanced companies in the field of IT technologies - Microsoft, Apple, Intel and others. In the process of conducting research, one task was pursued - to find a universal port that could be used for most devices.

Thus, users were provided with a USB connector, which was almost immediately supported by various developers and began to be actively used in the most different devicesah, starting from personal computers And ending with mobile gadgets. However, it happened that the cables with such connectors could be used far from everywhere, and they themselves were different, in connection with which some need a mini-USB connector to make the appropriate adapter.

At the same time, few people know how this procedure should be implemented correctly.

The concepts you need to know

The splitting of the USB connector begins with the study of basic concepts:

• VCC - contact of the positive potential of the power supply. For modern USB cables, the indicator of this contact is +5 volts, it should be noted that in radio-electric circuits such an abbreviation fully corresponds to PNP power voltage, as well as NPN transistors.
• GND - contact negative power supply potential. In modern equipment, including also various models motherboardsThis device is connected to the housing in order to ensure its effectively protection against static electricity or any external sources of electromagnetic interference.
• D- - information contact having zero potential relative to which information is translated.
• D + - informational contact having a logical unit. This contact is used to broadcast information from the host to the device or vice versa. At the physical level, this process is the transfer of rectangular pulses with a positive charge, while the impulses have different amplitudes and diet.
• Male is the plug of this connector, which among modern users, which is carried out with a USB connector for mouse and other devices, is often called "dad".
• Female - the socket in which the plug is inserted. Users are called "Mom".
• RX - receiving information.
• TX - information transfer.

USB-OTG.

OTG is a method of connecting through a USB cable of two peripheral devices without the need to use the computer. Also, such a flashing micro-USB connector in professional circles is often called USB-Host. In other words, a flash drive or some hDD Thus, can directly connect to the tablet or mobile phone Just as a full-fledged personal computer.

In addition, mice or keyboards can be connected to the gadgets if they support the possibility of using them. Often, it is often connected to cameras and other gadgets with printers.

What is the restrictions?

Restrictions that have such a flashing micro USB connector are as follows:

For example, if we are talking about connecting to a telephone of some USB flash drive, then in this case the "USB_AF-USB_AM_MICRO" adapter is most often used. In this case, a flash drive is inserted into the connector, while the plug connects to the mobile phone.

Feature cable

The main feature, which is distinguished by the splitting of the USB connector into OTG format, is that in the pin 4 plug, it must be closed with contact 5. In a standard data cable, this contact is not soldered at all, but is called this USB-BM plug Micro. It is for this reason that you need to get to the fourth contact, after which the jumper to attach it to the GND wire. After such a procedure, the plug will be renamed USB-AM Micro. It is precisely the presence of jumpers between these contacts in the plug allows the device to determine which one peripheral device is collected to it. In the event that this jumper does not see the device, they will be part of a passive device, and any flash drives connected to it will simply be completely ignored.

How are devices defined?

Many believe that when connected in OTG mode, both devices are fully automatically determined by which of them will be a host, and who will be subordinate. In fact, in this case, only the user defines the one who is in this case will be the master, since some device will stick a plug, equipped with a jumper between 4 and 5 contacts, then from them will be a host.

How to do it?

Through translucent isolation, you can consider several multi-colored wires. You will need to bore insulation near the black wire, after which one end of the jumper to fall to the GND contact. From the opposite side, you can see the white wire, as well as unused contact. In this case, we need to be improved isolation near the unused contact, after which it is to fall to it the second end of the jumper.

It is worth noting that the MICRO format USB displacement circuit is much simpler.

Running plug that you equipped with a jumper will need to be isolate, for which a specialized heat shrink tube is used. After that, you will need to just take "mom" from the extension cord and solder it to our plug color in color. If cables are shielded, then in this case you will need also, among other things, connect and screens.

Is it possible to charge?

If the device is connected to the device through OTG, then in this case it will have to feed it, which can significantly reduce the overall duration of the device from the battery built into it. In this regard, many are thinking about whether it is possible through external source Recharge such a device. It is possible, but for this you need support special regime In the device, as well as a separate splitting of the USB connector for charging.

In fact, charging mode is most often envisaged by modern gadget developers, but not all allow such a procedure. At the same time, it should be noted that to transition to such a charging mode, a separate disintegration diagram of the USB connector should be used, in which the contacts are closed through a separate resistor.

Problems When charging various devices via USB often occur when non-standard chargers are used. In this case, the charging occurs quite slowly and is not completely absent.

It should be said that charging via USB is not possible with all mobile devices. This port has only for data transfer, and a separate round nest is applied to charging.

The output current in computer USB is not more than half an ampere for USB 2.0, and for USB 3.0 - 0.9 A. A row of devices can be not enough for a normal charge.

It happens that there is a charger at your disposal, but it does not charge your gadget (it can report inscription on the display or there will be no charge indication). This memory is not supported by your device, and perhaps this is due to the fact that a number of gadgets prior to the start of the charging process scans the presence of a certain voltage on Pins 2 and 3. For other devices, the presence of jumpers between these pins may be important for other devices, as well as their potential.

Thus, if the device does not support the proposed charger type, the charging process will never begin.

In order for the device to start charging from the charger provided to him, it is necessary to provide 2 and 3 USB kicks, the necessary voltages. For different devices, these voltages may also differ.

For many devices, pins 2 and 3 have a jumper or resistance element, which is not more than 200 ohms. Such changes can be made in the USB_AF slot, which is in your zoom. Then the charging will be possible to produce a standard DATA cable.

The Freelander Typhoon PD10 gadget requires the same connection scheme, but the charge voltage should be at the level of 5.3 V.

If the charger does not have a USB_AF jack, and the cord comes directly from the housing, you can ship the mini-USB or Micro-USB plugs. Connections must be made as shown in the following image:

Different Apple products have such a connection option:

In the absence of an element of resistance with a denomination of 200 kΩ on Pans 4 and 5, Motorola devices cannot make a complete charge.

For charging Samsung. Galaxy requires a jumper on pines 2 and 3, as well as a resistance element for 200 kΩ on contacts 4 and 5.

Full charge samsung Galaxy Tab. In gentle mode, it is recommended to produce when using two resistors with a par value of 33 kΩ and 10 kΩ, as shown in the picture below:

Such a device as E-Ten can be charged by any memory, but only under the condition that pins 4 and 5 will be connected by a jumper.

This scheme is implemented in USB-OTG cable. But in this case, you need to use an additional USB dad-dad adapter.

Universal memory Ginzzu GR-4415U and other similar devices have nests with various compound Resistors for charging devices iPhone / Apple and Samsung / HTC. The pinout of these ports looks like this:

To charge navigator Garmin.It is necessary that the same cable with a jumper on contacts 4 and 5. But in this case, the device cannot be charged during operation. In order for the navigator to recharge, it is necessary to replace the jumper on the resistor with a par value of 18 com.

To charge tablets, it is usually necessary to 1-1.5 A, but as mentioned earlier, USB ports will not be able to normally charge them, since USB 3.0 will give a maximum of 900 mA.

In some models, charging tablets have a circular coaxial socket. Plus PIN MINI-USB / Micro-USB socket in this case does not have connections to the battery charge controller. According to some users of such tablets, if you connect the plus from the USB socket with a plus coaxial jumper, the charging can be carried out via USB.

And you can make an adapter to connect to a coaxial socket, as shown in the figure below:

Here are the diagrams of jumpers with the voltage and ratings of the resistors:

As a result, to carry out the charging of various gadgets from non-versions, you need to make sure that the charging gives the voltage 5 V and current at least 500 mA, and make changes to the nest or uSB plug According to the requirements of your device.

Convenient storage Radioetals

USB connector is universal sequential tire. Today, this connector in various form factor is present on almost any electronic gadget or device. However, in view of long-term operation, a negative situation may occur - the connector either is chosen or disappeared (when taking into account the presence of high temperatures).

Read more about how to replace the connector in the following article. It should be remembered that the whole method is given if you are applied, then only at your own risk! As a rule, when the unprofessional tries to independently repair the complex electronics, everything ends with extremely deplorable.

Many professionals in the event of the situation described above are advised to acquire a new connector. For the price it is worth the dear penny. Sold in any computer cabin.

In order not to confuse the connector with anything, it is better to go shopping with the old connector (which fell off). You need to purchase exactly the same. The following is a set of tools that will necessarily need to perform the replacement of the connector:

• flux for soldering;
• soldering iron with a thin stale;
• rosin;
• solder.

The standard UBS connector has several conclusions. It is imperative that these conclusions fall into the transition holes that are intended for them. But before placing a connector on a fee, it is recommended to clean the contacts.

This is performed using an ordinary rubber elasty, which is used to remove a simple pencil from paper. This will exclude the possibility of bad contact after soldering.

It should be immediately noted that the conclusions are recommended in such a way as not to stick out of the extra solder. After all, it conducts electricity, and therefore, can close to the ground in case of incorrect installation of the board in a laptop (or any other device).

To unprofessional perform the soldering in the correct way, it is recommended to use a flux or rosin. It will give the opportunity to do not stick to the suggestion of the soldering iron.

As a result, the soldering will be accurate and durable.

It is extremely important not to overheat the fee during the soldering. After all, there are paths. When overheated, they can rise that will break all the operation of the device.

The video will be demonstrated how you can independently replace the USB connector on the laptop:
