This is basically a module similar to FTDI/FT232RLbasic breakout board. CH340 is a series of USB bus adapters, that provides serial, parallel or IrDA interfaces over the USB bus (note: CH340G supports serial interface only). The CH340G integrate circuit provides common MODEM signals to allow adding a UART to a computer or converting existing UART devices to USB interface.Most of the Chinese Arduino nano boards have the CH340G chip. After assembling the kit, I tested it with an ESP8266 module and it worked.The schematic of the kit:The kit package includes these components.
