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
