Driver Installation Tip
Connect the device to the PC and open the device manager to install the FTDI driver . For Windows 10, download the driver files matching your OS, unzip them, and install them through the device manager. (Note: In some system environments, the driver may need to be installed twice to take effect. Unrecognized devices are usually named M5Stack or USB Serial. Windows recommends using driver files for direct installation in the device manager (custom update); executable installation may not work properly). Click here to download the FTDI driver
