  1. Visit the GitHub repository or download the project zip file from this link.

  2. The package includes the latest firmware binary, local flashing tools, and driver files.

  3. Extract the package to a local folder that is easy to access.

  4. Use the local package when:

    • the online flasher cannot detect your board

    • you need the Windows Flash Download Tools workflow

    • you are using the macOS local flashing workflow

Before flashing locally, make sure the CP210x driver is installed. Please refer to Driver Installation for driver installation instructions.
