About CH343
CH343 is a USB bus adapter chip, realizes USB to high-speed asynchronous serial port and supports up to 115200bps communication 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.
How to use
Windows
For most of the PC, the driver for CH343 is CDC by default, if you need to use the VCP driver, please download the driver and install it manually.
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, and 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:
ls /dev/tty*
The port should be named ttyACM0, user can use the minicom tool to test.
sudo apt-get install minicom -y minicom -D /dev/ttyACM0
MacOS
To use with MacOS, please download the driver and follow the guide:
Android
To use it with an Android device, please download the APP and test it.
3. Set the parameters to use.
