Onboard Interface
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.
How to use
Windows
CDC Driver
The default driver of the computer is the CDC driver, which can be viewed through the device manager.
We default to software flow control, if you need to use CDC hardware flow you need to connect the board's CFG to EN (power on self-detection).
VCP Driver
The VCP driver is a vendor driver and needs to be installed by yourself. It can be viewed through Device Manager after installation.
The default is software flow control, if you need to use VCP hardware flow, you can open it directly through the serial debugging assistant.
Linxu/Raspberry Pi
To work with Raspberry Pi, it is driver-free, just connect and check with the following command:
ls /dev/tty*
The port should be named ttyACM0, user can use the minicom tool to test.
minicom -D /dev/ttyACM0
MacOS
First click to download the CH343 driver for MacOS.
Driver installation guide: MacOS guide
Open the serial assistant after installation (Directly download the serial assistant online through MAC).
Android
To use it with an Android device, please download the APP and test it.
1. Open the APP and click to scan the device.
2. Click the scanned device.
3. Set the parameters to use.
