Usb Micro B Cable Pinout

Also it is the same for micro usb type a and micro usb type b.

Usb micro b cable pinout.

Similar to the usb a connector the b type connector uses the friction to retain the connector in place. Nrzi non return to zero invert encoding scheme used to send data with a sync field to synchronise the host and receiver clocks. 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.

A broad variety of usb hardware exists including several different connectors of which usb c is the most recent. 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. Micro usb cable uses 4 shielded wires. The pinout diagram for the micro usb type b very similar to usb type a except for the last two pins 4 and 5.

The usb device that uses full speed bandwidth devices must have a twisted pair d and d conductors. Two for power 5v gnd two for differential data signals labelled as d and d in pinout. The data is transferred through the d and d connectors while vbus and gnd connectors provide power to the usb 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 pin no 1 is 5v acts as a source to the device or source from the device.
