Maix Bit USB Driver Installation


Linux does not need to install the driver, the system comes with it, use ls /dev/ttyUSB* to see the device number


The development board is divided into two versions, new and old, and different drivers need to be installed separately

Maix Bit (old version)

Windows download ch340 ch341 driver and install it, then you can see the serial device in the Device Manager

Maix Bit new version with microphone (use CH552) development board

The development board uses the CH552 chip to realize the USB to serial port function. There is no JTAG simulation function. Windows needs to install the special driver.

When we get the MaixPy development board and connect it to the computer, we can open the device manager to check whether the serial port driver has been installed. The methods to open the device manager are:

  • This computer (right click) -> Properties -> Device Manager
  • Start menu (right click) -> Device Manager
  • Control Panel -> (Search) Device Manager
  1. When our system is a Windows 10 system, the system will automatically install the driver for us, and if it is an old version of Win7, win8, we need to install the USB driver manually:

  2. Open the link in the previous section to download the driver

  3. Click Install

  4. After the installation is complete, you can see in the device manager that two serial devices have been identified (only one serial port is available)
