CH340 USB To RS232 TTL Auto Converter Module Serial Port FOR Arduino

 About this item

    This product is a TypeC to TTL serial port module that uses a CH340N USB bus adapter chip
    There are three indicator lights on the board, one for power, and the other two for communication.
    Because there is no serial port on our current computer, we generally use a USB to serial port module for only one purpose, to map the computer's USB port to a serial port
    Before use, please confirm whether the TYPE-C cable has data transmission function.
    The module directly outputs 5V voltage, but it can also be connected to the 3.3V pin of other devices for communication. For example, other CH340G serial port modules can be connected to send and receive data
