Firmware Flashing

Option 1: One-click script (Windows)

update-arduino-firmware.bat

The script uses avrdude to flash galaxy-rvr.ino.2.0.0.hex.

Option 2: Arduino IDE

Open galaxy-rvr/galaxy-rvr.ino, compile and upload.

ESP32-CAM firmware

The AI Camera module requires its own firmware. See ai-camera-firmware for source and instructions.
