Power on
Power on is designed to use an external power-on switch. The external switch turns on one board; this board then turns on slave boards.
The physical on-off switch on the Teensy board is shorted in on-position.
Power off
Raspberry Pi initiates turn off, which orders Teensy (boards) to turn off after the Raspberry shutdown. A request power off button will tell the Raspberry that it is time to shut down.
Do not use the battery's power-off feature except in emergencies (e.g., if the battery is totally flat or something is burning).

The teensy PCB (green light) is for steering and crane-yaw.
The Raspberry (at the bottom of image) is for the Lidar and the D455 3D camera.
