Motor drive PCB version 1,.2
Figure 1. Pcb version 2.1 with plug usage.
Figure 2. Teensy circuit version 2.1 for four motor controls.
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.
