How to Use
Driver Installation
Connect the device to the PC, open the device manager to install FTDI driver for the device. Take the win10 environment as an example, download the driver file that matches the operating system, unzip it, and install it through the device manager. (Note: In some system environments, the driver needs to be installed twice for the driver to take effect. The unrecognized device name is usually M5Stack or USB Serial. Windows recommends using the driver file to install directly in the device manager (custom Update), the executable file installation method may not work properly). Click here to download FTDI driver
For MacOS users, please tick System Preferences -> Security and Privacy -> General -> Allow downloadable apps from the following locations -> App Store and Approved Developer Options.
