USB 3 Type C pinouts and signals

USB Type-C is a USB specification for a small 24-pin reversible-plug connector for USB devices and USB cabling.

The USB Type-C Specification 1.0 was published by the USB Implementers Forum and was finalized in August 2014. It repeats roughly the same time as the USB 3.1 specification.

Communication is full-duplex during SuperSpeed. In the compatibility mode (USB 1.0 or USB 2.0) communication is half-duplex, with direction controlled by the host.

The USB Type-C connectors can connect both hosts and devices. This connector is vaery small and become a very polular in various mobile devices.
