This is a CH340G breakout board, designed to allow the addition of a USB connection to your project. Furthermore this opens up the ability to program microcontrollers such as the Arduino Pro mini. This module allows you to connect up your project, from programming small microcontrollers to a personalised computer keyboard.
Included with the module is a jumper for performing a loopback test and setting a particular logic level.
The module is arranged for the use of a UART connection. This may require a driver to be installed, however this is a standard driver that is distributed by Microsoft Windows Update, available on Linux and can be configured in MAC OS.
