تراشه مبدل USB به سریال CH340T پکیج SMD

CH340 is a USB bus convert chip and it can realize USB convert to serial interface, USB convert to  IrDA infrared or USB convert to printer interface.  In serial interface mode, CH340 supplies common MODEM liaison signal, used to enlarge  asynchronous serial interface of computer or upgrade the common serial device to USB bus directly. More  detail about USB convert to printer interface please referring to the second manual CH340DS2.  In infrared mode, add infrared transceiver to CH340 can compose USB infrared adapter, realize SIR  infrared communication.
