Description

This is mainly used as a USB serial converter and provides drivers compatible with a variety of devices. This allows you to easily set up a connection and data communication with your computer.

CH340G supports USB 2.0 full-speed interface and supports serial communication speeds of up to 2Mbps. This chip has drivers available for a variety of operating systems (Windows, Mac, Linux).
Functions :

CH340 is a series of USB bus adapters, that provides serial, parallel or IrDA interfaces over
the USB bus (note: CH340G supports serial interface only). The CH340G integrate circuit
provides common MODEM signals to allow adding a UART to a computer, or converting
existing UART devices to USB interface.

Pinout :
