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

    Power and elegance in a wonderfully small package.

    I love this tiny device! There is so much tech crammed into this perfectly designed form factor, it blows my mind. I have been using mine to work on development of AtomVM - an exciting new development platform that runs Erlang and Elixir on the ESP32 (project can be found on GitHub), and this has been the perfect device to keep with me so I can continue development work when I travel. There are so many potential uses for this device using just the onboard peripherals I look forward to exploring all of those possibilities.
