this product is a TypeC to TTL serial port module, using CH340N USB bus transfer chip, there are 3 indicator lights on the board, one is a power indicator, and the other two are communication indicator lights. Because there is no serial port on our current computer, we generally use USB to serial port module for only one purpose, mapping the USB port of the computer to serial port.

Note:
1. Please confirm whether the Type-C line has data transmission function before use.
2. The module directly outputs 5V voltage, but it can also connect the 3.3V pin of other equipment for
communication. For example, it can connect other CH340G serial port modules
