Flashing Pre-Compiled Firmware

If you do not need to modify the source code and want to get your FlatSat board running immediately, you can flash the pre-compiled production binary.

1. Connect the board to your computer via USB.
2. Enter the board into bootloader mode. This will open RP2040’s mass storage folder on your computer.
3. Download the latest flatsat-vx.x.x.x.uf2 file from the flatsat-ground-station repository.
4. Drag and drop the flatsat-vx.x.x.x.uf2 file into RP2040’s mass storage folder. The mass storage folder will be closed once the firmware is uploaded correctly.
