CH340 is a USB converter in two directions as follows:
- USB to serial port interface.
- USB to printer interface.
- In the serial interface port, the CH340 provides a normal MODEM signal and is used to scale the serial interface of the computer asynchronously or to upgrade the serial device during the USB signal transmission. direct.
- For more information on the USB adapter, refer to the product CH340DS2.
- In the infrared port, the CH340 is added to a transceiver that can create a USB adapter or SIR. more).
Characteristics:
- The speed of the USB device interface port, in line with the USB 2.0 specification.
- Simultaneous serial interface simulator, used to upgrade old peripherals via USB.
- Perfectly suited for serial applications in PC devices running on Windows.
- Two-way serial interface, set up the transceiver signals, support different communication rates from 50bps to 2Mbps.
- Supports common MODEM signals such as RTS DTR, DCD, RI, DSR and CTS.
- Additional conversion devices such as RS232, RS485, RS422 and other interfaces.
- Full support for infrared IrDA SIR interfaces and transmission rates vary from 2400 bps to 115200 bps.
- Through the USB serial interface converter, the CH340 only fits in the relative level of the application program.
- The software is compatible with CH341, using direct drive of CH341.
- Supports 5V and 3.3V power supply
