About CH343
CH343 is a USB bus adapter chip, that realizes USB to a 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
CDC
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 CFG of the board to EN (power-on self-test).
VCP Driver
The VCP driver is a manufacturer driver and needs to be installed by the user. After installation, it can be viewed through Device Manager.
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
To use with MacOS, please download the driver and follow the guide:
Android
To use with an Android device, please download the APP and test.
1. Open the APP and click to scan the device.
2. Click the scanned device.
3. Set the parameters to use.
