Usb Micro B Cable Pinout

Universal serial bus usb is an industry standard that establishes specifications for cables and connectors and protocols for connection communication and power supply interfacing between computers peripherals and other computers.

Usb micro b cable pinout.

The pinout diagram for the micro usb type b very similar to usb type a except for the last two pins 4 and 5. A broad variety of usb hardware exists including several different connectors of which usb c is the most recent. The pin no 1 is 5v acts as a source to the device or source from the device. Usb a b 2 0 and 3 0 cable pinout the usb cable provides four pathways two power conductors and two twisted signal conductors.

The usb 3 0 micro b plug effectively consists of a standard usb 2 0 micro b cable plug with an additional 5 pins plug stacked to the side of it. The usb b type socket is an upstream connector that is only used on peripheral devices. Also it is the same for micro usb type a and micro usb type b. The usb device that uses full speed bandwidth devices must have a twisted pair d and d conductors.

Micro usb cable uses 4 shielded wires. In usb data cable data and data signals are transmitted on a twisted pair. Similar to the usb a connector the b type connector uses the friction to retain the connector in place. Two for power 5v gnd two for differential data signals labelled as d and d in pinout.

In this way cables with smaller 5 pin usb 2 0 micro b plugs can be plugged into devices with 10 contact usb 3 0 micro b receptacles and achieve backward compatibility.
