Ok. I see the problem. To recover board - some tricky setup is required.

1. Prepare empty Mini Lab with “labboard_update.ino” loaded to TotemDuino.
   (no need to remove boards from frame).
   

   

2. Connect jumper cables accordingly:
   (red) D0 → TXD
   (brown) D1 → DIG2
   (yellow) GND → RST (6 pin header)
   (orange) 3V3 → Nothing (leave hanging)
   
   

   

3. Plug in DC adapter to TotemDuino.

4. Now tricky step:
   • Touch second pin from bottom with (orange) wire, connected to 3V3.
   • Unplug (yellow) wire from GND and remove wire from pin.
   0.5v LED will probably light up, indicating LabBoard is in boot state. If not - continue still.
   

   
   
   
   

5. Click Reset button on TotemDuino and wait a few seconds. It should upload the firmware.
