- Disconnect the 12V power plug from the DryBox.
- Disconnect the heater plug, so the heater can't turn on while flashing.
- Press and hold the BOOT button on the DryBox v2 board.
- While holding BOOT, connect the USB-C cable to your computer.
- All LEDs should stay off. Your computer now shows a new serial (COM) port.
3Connect and install
Before you flash
- Flashing erases all settings (WiFi, PID values, device name). Write down any custom values first.
- After flashing, unplug USB and fully power-cycle the board, then run the Safety Check before using the heater.
