Usb Micro B Cable Pinout

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.

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. The pin no 1 is 5v acts as a source to the device or source from the device. 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.

Usb a b 2 0 and 3 0 cable pinout the usb cable provides four pathways two power conductors and two twisted signal conductors. Type b usb connector pinout the usb b type connector is almost square in shape but it has slightly bevel on the corners on the top ends of the connector. Nrzi non return to zero invert encoding scheme used to send data with a sync field to synchronise the host and receiver clocks. The data is transferred through the d and d connectors while vbus and gnd connectors provide power to the usb device.

Similar to the usb a connector the b type connector uses the friction to retain the connector in place. A broad variety of usb hardware exists including several different connectors of which usb c is the most recent. 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.

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.
