==Function Description==
 +
The CH344 chip provides 4 sets of asynchronous serial ports UART0/1/2/3. Each set of serial ports includes pins such as TXD, RXD, CTS, and RTS, enabling both 3-wire serial communication and 5-wire serial communication. Each asynchronous serial port supports hardware automatic flow control with CTSx and RTSx. You can configure them to enable or disable simultaneously using the CFG pin (default is disabled), or you can independently configure them using the VCP vendor driver demo.

===VCP Driver===
CH343 is a USB bus adapter chip, realizes USB to high-speed asynchronous serial port, and supports up to 115200bps communication

The VCP driver is a vendor driver and needs to be installed by yourself. It can be viewed through Device Manager after installation.<br/>
Automatic identification and dynamic self-adaptation of baud rate, providing common MODEM contact signals for expanding asynchronous serial ports of computers, or feature USB bus for the common serial device or MCU.

The default is software flow control, if you need to use VCP hardware flow, you can open it directly through the serial debugging assistant.
===Windows===

For most of the PC, the driver for CH343 is CDC by default, if you need to  use VCP driver, please download the driver and install munually.<br />

==Linxu/Raspberry Pi==
The CH343 USB UART board use software flow control by default, if you want to use hardware flow control, connect CFG to EN for CDC mode, set in SSCOM software for VCP mode.
 
===Linxu/Raspberry Pi===
 
 
To work with Raspberry Pi, it is driver-free, just connect and check with the following command:
