Re: reverse-voltage protection

Using a shunt does seem to be the easiest method. The trouble with that is those auto-resetting breakers. (You want this to trip fast, not take two seconds)
So, this would require an inline fuse with tight trip characteristics.

Considering that the PWM drivers seem to be the most sensitive, I would still put a diode in front of the 3.3v and 5v voltage regulators.
