This is a very small size of the USB to TTL serial module. The module uses the Micro USB interface and is compatible with the Ardriod data line. The width of the module is equal to the width of the Android data line plug. It is very convenient to insert it directly on the data line Micro USB plug. Compared to the use of the A type USB common head interface, the USB transfer TTL module on the PC is directly inserted. This module is more convenient to connect the other serial ports, such as the development board.
    The module is based on the CH340 chip, which is exactly the same as that of the CH340G and CH340T chips. The module can be used for downloading MCU downloaded programs such as STC MCU and other supporting serial port downloader programs, or as serial communication lines between PC and MCU, which is stable and reliable.
