USB-to-UART 5V/3V3 Adapter: how does it work?

The USB-to-UART Adapter is equipped with a CH340 chip appearing on your PC as a serial type device, and allows you to establish a serial type communication between your computer and your UART-equipped microcontroller board.

This adapter has been designed to modulate its logic voltage (3.3 or 5 V) by means of a simple switch. It works with a 5 V power supply via USB.
