CH340 is a USB bus convert chip and it can realize USB convert to serial interface, USB converts to IrDA infrared, or USB convert to printer interface.
In serial interface mode, CH340 supplies a common MODEM liaison signal, used to enlarge asynchronous serial interface of a computer or upgrade the common serial device to USB bus directly.


  1. Full speed USB device interface conforms to USB Specification Version 2.0, only needs crystal and capacitance external. Emulate standard serial interface, used to upgrade the former peripheral device, or add excess serial interface through USB.
  2. Totally compatible with serial application program in computer endpoint Windows operation system. Hardware full duplex serial interface, set transceiver buffer, supports communication baud rate varies
  3. from 50bps to 2Mbps.
  4. Supports common MODEM liaison signal RTS, DTR, DCD, RI, DSR, and CTS.By adding level converter equipment to supply RS232, RS485, RS422 and other interface.Supports IrDA criterion SIR infrared communication, supports baud rate varies from 2400bps to
  5. 115200bps.
  6. For it is through USB converts to serial interface, only compatible with the application layer not totally.
  7. Software compatible with CH341, using the drive of CH341 directly.
  8. Support 5V and 3.3V source voltage.
  9. Supply SSOP-20 package without lead, compatible with RoHS.
