USB to TTL based on CH340N

 
Overview
The CH340N chip is a USB-to-serial converter chip that converts data from a USB interface into serial data and communicates with other devices via a serial port (TTL level). When a computer sends data via USB, the CH340N converts it into serial data and sends it to the target device through its serial port pins; conversely, it can convert serial data received from the target device into data recognizable by the USB interface and then transmit it to the computer.
