Pinout of micro usb by color. Micro-USB pinout and connector pinout. Pinout of USB connectors for Garmin navigator

Content:

In every computer and other similar devices, the USB connector is the most popular. With the help of yusb wires, it became possible to connect more than 100 units of serially connected devices. These buses allow you to connect and disconnect any devices, even while a personal computer is running. Almost all devices can be charged through this connector, so there is no need to use additional power supplies. USB pinout the colors help to determine exactly what type of device a particular bus belongs to.

USB device and purpose

The first ports of this type appeared in the nineties of the last century. After a while, these connectors were updated to the USB 2.0 model. The speed of their work has increased more than 40 times. Currently, computers have a new USB interface 3.0 at a speed 10 times faster than the previous version.

There are other types of connectors of this type, known as micro and mini USB, which are used in modern phones, smartphones, and tablets. Each bus has its own or pinout. It may be required if you need to make an adapter with your own hands from one type of connector to another. Knowing all the subtleties of the location of the wires, you can even make Charger for a mobile phone. Please be aware, however, that the device may be damaged if connected incorrectly.

The USB 2.0 connector is designed as a flat connector with four pins. Depending on the purpose, it is labeled as AF (BF) and AM (BM), which corresponds to the common names "mom" and "dad". In mini and micro devices there is the same marking. They differ from ordinary buses by five contacts. USB device 3.0 outwardly resembles the 2.0 model, with the exception of the internal design, which already has nine contacts.

Pinout-wiring of USB 2.0 and 3.0 connectors

The pinouts for the USB 2.0 model are in the following order:

Red conductor to which power supply voltage is supplied direct current with a value of + 5V.
White conductor used to transfer information data. It is identified by the “D-” mark.
The conductor is colored green. With its help, information is also transmitted. It is marked as "D +".
The conductor is black. Zero supply voltage is applied to it. It is called its general wire and is designated by its own label in the form of an inverted T.

The wire layout in Model 3.0 is completely different. The first four contacting wires fully correspond to the USB 2.0 connector.

The main difference between USB 3.0 is the following wires:

Conductor # 5 has Blue colour... It transmits information with a negative value.
Conductor No. 6 is yellow, just like the previous contact, is designed to transmit information that has a positive value.
Conductor # 7 is used as an additional ground.
Conductor # 8 is purple and conductor # 9 is orange. They perform the function of receiving data, respectively, with negative and positive values.

Wiring-pinout of micro- and mini-USB connectors

Micro USB connectors are most commonly used in tablets and smartphones. From standard tires pinout micro usb differ significantly in size and the presence of five contacts. They are labeled as micro-AF (BF) and micro-AM (BM), which corresponds to "mom" and "dad".

The micro-USB is wired in the following order:

Contact No. 1 is red. Voltage is supplied through it.
Contacts # 2 and # 3 white and green are used for transmission.
The lilac pin No. 4 has a special function in individual bus models.
Black pin No. 5 is a neutral wire.

The pinout of the mini USB connector by color is the same as in the micro USB connectors.

It has been developed since 1994, while the development team consisted of engineers from leading companies in the field of IT technologies - Microsoft, Apple, Intel and others. In the process of conducting research, one task was pursued - to find universal port which 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 devices from personal computers to mobile gadgets. However, it so happened that cables with such connectors could not be used everywhere, and by themselves they were different, and therefore some require the wiring of the mini-USB connector in order to make the appropriate adapter.

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

Concepts to know

Wiring the USB connector begins with learning the basic concepts:

VCC - positive potential contact For modern USB cables, the indicator of this contact is +5 Volts, while it is worth noting that in radioelectric circuits this abbreviation fully corresponds to the supply voltage PNP, as well as NPN transistors.
GND - contact of the negative potential of the power supply. In modern equipment, including also various models motherboards, this device connects to the enclosure to provide effective protection against static electricity or any external sources of electromagnetic interference.
D- - information contact with zero potential, relative to which information is broadcast.
D + - informational contact, which has a logical unit. This contact is used to broadcast information from the host to the device, or vice versa. On the physical level this process is the transmission of rectangular pulses with a positive charge, while the pulses have different amplitudes and duty cycles.
Male - the plug of this connector, which is among modern users, which is used to unsolder the USB connector for the mouse and other devices, is often called "dad".
Female - The jack into which the plug is inserted. The users are called "mom".
RX - information reception.
TX - information transfer.

USB-OTG

OTG is a method of connecting two peripheral devices without the need for a computer. Also, such wiring of a micro-USB connector is often called a USB-host in professional circles. In other words, a flash drive or some kind of hard drive can thus be directly connected to a tablet or mobile phone in the same way as to a full-fledged personal computer.

In addition, mice or keyboards can be connected to gadgets, if they support the ability to use them. Often, cameras and other gadgets are connected to printers in this way.

What limitations does it have?

The limitations that such a pinout of the micro-USB connector has are as follows:

For example, if it comes about connecting a USB flash drive to the phone, then in this case the adapter "USB_AF-USB_AM_micro" is most often used. In this case, a USB flash drive is inserted into the connector, while the plug is connected to a mobile phone.

Cable feature

The main feature that distinguishes the pinout of the USB connector in the OTG format is that pin 4 in the plug must be closed with pin 5. In a standard data cable to this contact nothing is soldered at all, but this plug is called USB-BM micro. It is for this reason that you need to get to the fourth contact, and then use a jumper to connect it to the GND wire. After this procedure, the plug will be renamed to USB-AM micro. It is the presence of a jumper between these contacts in the plug that allows the device to determine that some kind of peripheral device is going to be connected to it. If the device does not see this jumper, it will act as a passive device, and any flash drives connected to it will simply be completely ignored.

How are devices identified?

Many people believe that when connected in OTG mode, both devices fully automatically determine which of them will be the host and who will be subordinate. In reality, in this case, only the user determines who exactly will be the master in this case, since a plug equipped with a jumper between 4 and 5 contacts will be plugged into which device, then one of them will be the host.

How to do it?

Through the translucent insulation, you can see several colored wires. You will need to melt the insulation near the black wire, then solder one end of the jumper to the GND pin. On the opposite side, you can see a white wire, as well as an unused contact. In this case, we need to melt the insulation near the unused contact, and then solder the other end of the jumper to it.

It is worth noting that the wiring diagram for the micro USB connector is much simpler.

The open plug that you equipped with a jumper will need to be insulated, for which a specialized heat shrink tubing is used. After that, you just need to take the "mother" from the extension cord and solder it to our plug color in color. If the cables are shielded, then you will also need to connect the shields, among other things.

Can i charge?

If peripherals are connected to the device via OTG, then in this case it will have to power it, which can significantly reduce the overall duration of the device from the built-in battery. In this regard, many are wondering whether it is possible to recharge such a device through an external source. This is possible, but this requires support for a special mode in the device, as well as a separate pinout of the USB connector for charging.

In fact, the charging mode is most often provided by modern gadget developers, but not everyone allows such a procedure. At the same time, it should be noted that to switch to this charging mode, a separate wiring diagram for the USB connector must be used, in which the contacts are closed through a separate resistor.

Most modern mobile phones, smartphones, tablets and other wearable gadgets, supports charging via USB mini-USB or micro-USB. True, there is still a long way to a single standard, and each company is trying to make the pinout in its own way. Probably to buy the charger from her. Well at least the YUSB plug and socket were made standard, as well as the supply voltage of 5 volts. So having any charger adapter, you can theoretically charge any smartphone. How? and read on.

Pinout of USB connectors for Nokia, Philips, LG, Samsung, HTC

The brands Nokia, Philips, LG, Samsung, HTC and many other phones recognize the charger only if the Data + and Data- contacts (2nd and 3rd) are short-circuited. You can short-circuit them in the USB_AF socket of the charger and easily charge your phone via a standard data cable.

Pinout of USB connectors on the plug

If the charger already has an output cable (instead of an output jack), and you need to solder a mini-USB or micro-USB plug to it, then you do not need to connect 2 and 3 pins in the mini / micro USB itself. In this case, you solder plus to 1 contact, and minus to the 5th (last).

Pinout USB connectors for Iphone

For iPhones, Data + (2) and Data- (3) contacts must be connected to GND (4) through 50 kOhm resistors, and to + 5V through 75 kOhm resistors.

Samsung Galaxy charging connector pinout

To charge the Samsung Galaxy in the USB micro-BM plug, a 200 kΩ resistor must be installed between pins 4 and 5 and a jumper between pins 2 and 3.

Pinout of USB connectors for Garmin navigator

Your Garmin Navigator requires a dedicated data cable to power or charge. Just to power the navigator through the cable, you need to short-circuit 4 and 5 contacts in the mini-USB plug. For recharging, you need to connect 4 and 5 contacts through an 18 kOhm resistor.

Pinout schemes for charging tablets

Almost anyone tablet computer charging requires a large current - 2 times more than a smartphone, and charging through the mini / micro-USB socket in many tablets is simply not provided by the manufacturer. After all, even USB 3.0 will not give more than 0.9 amperes. Therefore, a separate nest is placed (often of a round type). But it can also be adapted to a powerful YUSB power source if you solder such an adapter.

Samsung Galaxy Tab charging socket pinout

For the right charge Samsung tablet Galaxy Tab recommend another circuit: two resistors: 33 kΩ between +5 and jumper D-D +; 10 kΩ between GND and jumper D-D +.

Charging port pinout

Here are some voltage diagrams for USB contacts indicating the value of the resistors allowing these voltages to be obtained. Where a resistance of 200 ohms is indicated, a jumper must be installed, the resistance of which should not exceed this value.

Charger Port Classification

SDP(Standard Downstream Ports) - Data exchange and charging, allows current up to 0.5 A.
CDP(Charging Downstream Ports) - data exchange and charging, allows current up to 1.5 A; hardware identification of the port type (enumeration) is performed before the gadget connects the data lines (D- and D +) to its USB transceiver.
DCP(Dedicated Charging Ports) - Charging only, allows current up to 1.5 A.
ACA(Accessory Charger Adapter) - PD-OTG operation is declared in Host mode (with connection to PD peripherals - USB-Hub, mouse, keyboard, HDD and with the possibility of additional power supply), for some devices - with the ability to charge PD during an OTG session ...

How to remake a plug with your own hands

Now you have a pinout diagram of all popular smartphones and tablets, so if you have the skill to work with a soldering iron, there will be no problems with converting any standard USB connector to the type you need for your device. Any standard charging based on using USB, provides for the use of only two wires - this is + 5V and a common (negative) contact.

Just take any charging adapter 220V / 5V, cut off the USB connector from it. The cut end is completely free of the shield, while the other four wires are stripped and tinned. Now we take a cable with a USB connector the right type, after which we also cut off the excess from it and carry out the same procedure. Now it remains to simply solder the wires together according to the diagram, after which the connection is isolated each separately. The resulting case is wrapped from above with electrical tape or tape. You can fill it with hot melt glue - also a normal option.

Bonus: all other connectors (sockets) for mobile phones and their pinouts are available in a single large table -.

The universal USB bus is one of the popular personal computer interfaces. It allows you to produce serial connection various devices(up to 127 units). Also, USB-buses support the function of connecting and disconnecting devices while the personal computer is running. In this case, the devices can receive power directly through the mentioned element, which frees from the need to use additional power supplies. In this article, we'll take a look at what a standard USB pinout is. This information may come in handy in the independent manufacture of any USB adapters or devices that receive power through the interface we are considering. In addition, we will analyze what is the pinout of micro-USB and, of course, mini-USB.

Description and pinout of the USB interface

Almost every PC user knows what a USB connector looks like. It is a flat four-pin Type A interface. The USB female is AF and the male is AM. The USB Type A pinout consists of four pins. The first wire is marked in red and is supplied with a DC voltage of +5 V. It is allowed to supply a maximum current of 500 mA. The second contact - white - is for (D-). The third wire (green) is also used for data transmission (D +). The last contact is marked in black, zero supply voltage is applied to it (common wire).

Type A connectors are considered active, powering the host is connected to them, etc.). Type B connectors are considered passive and are used to connect devices such as printers, scanners, etc. Type B connectors are square with two beveled corners. “Mom” is labeled BF and “Dad” is BM. The USB type B pinout has the same four pins (two at the top and two at the bottom), the purpose is identical to type A.

Wiring micro-USB connectors

Connectors of this type are most often used to connect tablets and smartphones. They are significantly smaller than a standard USB interface. Another feature is the presence of five contacts. The marking of such connectors is as follows: micro-AF (BF) - "mother" and micro-AM (BM) - "father".

Micro USB pinout:

The first contact (red) is designed to supply + 5 V supply voltage;

The second and third wires (white and green) are used for data transmission;

The fourth contact (ID) in type B connectors is not used, but in type A connectors it closes to the common wire to support the OTG function;

The last, fifth, contact (black) - zero supply voltage.

In addition to those listed, the cable may have one more wire used for "shielding"; no number is assigned to it.

Mini USB pinout

Mini USB connectors also contain five pins. These connectors are labeled as follows: mini-AF (BF) - "female" and mini-AM (VM) - "male". Pin assignment is identical to the micro-USB type.

Conclusion

The information on wiring for USB connectors is very relevant, since this type of interface is used in almost all mobile and desktop devices and gadgets. These connectors are used both to charge the built-in rechargeable batteries and for data transmission.

This article provides general information about the USB standard as well as pinoutUSB connector in all kinds of colors (USB, mini-USB, micro-USB, USB-3.0).

USB (Universal Serial Bus) connector- This serial bus universal purpose, modern way connections external devices to a personal computer. Replaces the previously used connection methods (serial and parallel port, PS / 2, Gameport, etc.) for common types of peripheral devices - printers, mice, keyboards, joysticks, cameras, modems, etc. Also, this connector allows you to organize the exchange of data between a computer and a video camera, card reader, MP3 - player, external hard drive.

The advantage of the USB connector over other connectors is the ability to connect Plug & Play devices without the need to restart the computer or manual installation drivers. Plug & Play devices can be plugged in while the computer is running and can be up and running within seconds.

When connecting a new device, the hub (cable hub) first receives high level on the data line, which reports that new equipment has appeared. Then the following steps follow:

The Hub informs the Host computer that a new device has been connected.
The host computer asks the hub to which port the device was connected to.
After receiving a response, the computer issues a command to activate this port and zeroes (resets) the bus.
The concentrator generates a reset signal (RESET) with a duration of 10 ms. The output current of the device is 100 mA. The device is now ready for use and has a default address.

The USB is a collaboration between Compaq, NEC, Hewlett-Packard, Philips, Intel, Lucent and Microsoft. USB standard was intended to replace the widely used RS-232 serial port. In general, USB makes the work easier for the user and has a large throughput than the RS-232 serial port. The first USB specification was developed in 1995 as a low-cost universal interface for connecting external devices that did not require a lot of data bandwidth.

Three USB versions

USB 1.1

The USB 1.1 version was designed to serve slow peripherals (Low-Speed) with a data transfer rate of 1.5 Mbps and fast devices (Full-Speed) with a data transfer rate of 12 Mbps. USB 1.1, however, was unable to compete with a high-speed interface, for example. FireWire (IEEE 1394) from Apple with data transfer rates up to 400 Mbps.

USB 2.0

In 1999, they began to think about the second generation of USB, which would be applicable to more complex devices (for example, digital video cameras). This a new version, designated as USB 2.0 was released in 2000 and provided a maximum speed of up to 480 Mbps in Hi-Speed mode and retained backward compatibility with USB 1.1 (data transfer type: Full-Speed, Low-Speed).

USB 3.0

The third version (also referred to as Super-speed USB) was designed in November 2008, but, probably due to the financial crisis, its mass distribution was delayed until 2010. USB 3.0 is more than 10 times faster than USB 2.0 (up to 5 Gbps). The new development has 9 wires instead of the original 4 (the data bus already consists of 4 wires), however, this standard still supports USB 2.0 and provides lower power consumption. This allows you to use any combination of USB 2.0 and USB 3.0 devices and ports.

The USB connector has 4 pins. A twisted pair (two wires twisted together) is connected to the DATA + and DATA- pins, and ordinary wires are connected to the VCC (+5 V) and GND pins. Then the entire cable (all 4 wires) is shielded with aluminum foil.

Below is the pinout (wiring) of all types USB connectors.
