The USB to TTL CH340 is a USB-to-serial converter module that uses the CH340 chip to convert USB signals to TTL (Transistor-Transistor Logic) level serial communication. It is commonly used to interface USB-enabled devices with TTL serial devices such as microcontrollers and development boards. This module provides a cost-effective and reliable solution for connecting TTL serial devices to a USB port on a computer.
