low voltage cutout works perfectly! All 6 drivers disabled when 12v supply drops to about 7.9v. The microcontroller is still functioning perfectly though at that input voltage, so it can still make decisions. Hurray! Time to put it back together now. I can't believe I made something that actually works!

Power consumption at 12v is about 620mA, so about 7watts. It's those 6 DC-DC's I think that makes it eat up more power. At 8v, it was using about 850mA.
