[edit] Motor drive PCB version 1,.2
Figure 1,2. Pcb with (most) plug functions.
Figure 3,4. The power on/off part of the circuit, with modifications for external on-switch and 3.3V for AS5147U SPI connectors.
[edit] Power on
Power on is modified to use an external switch. The external switch turns on one board; this board then turns on slave boards.
All bords that should turn on must have the physical switch in the on position.
To turn individual boards on, use the 'Power reset' button, with the switch on that board on and all other switches off.
[edit] Power off
Do not turn power off by operating the switch, if there is a Raspberry Pi operating on its power.
Power of should use the 'power off' command from each Raspberry, with an off delay, to allow the Raspberry to shut down nicely.
