Instructions

1. Download the MicroPython Installer for your operating system:

   • Windows: Download the .exe file labeled ‘Windows’ and run the installer.

   • macOS: Download the .zip file labeled ‘macOS’, extract the zip file, and move the application to your Applications folder.

   • Linux: Download the .deb file labeled ‘Linux’ and install it using your package manager:

     sudo dpkg -i [file name].

   • NuGet Package: Download the .nupkg file if you are using NuGet for package management.

2. Launch the Firmware Installer tool.

3. Let the installer detect your board

   

4. Press the ‘Install MicroPython’ button.

5. Wait for Installation. After a few seconds, your board will be ready to go!

If the installer doesn’t automatically find the MicroPython firmware, you can download it manually.
