This morning I did a quick design of a daughter board that can be used to adapt the current HIGH drive controller board (ver 0.1.3) to a LOW drive. The reason one might want to do this is to be able to control alternators which use a different field voltage then the other components. e.g.: a 48v alternator with a 12v starter, fuel pump, etc. is used.
Just mount this to a heat sink and connect the appropriate wires. And this, btw, is the final drive that I am revising the PCB artwork to. Not only is it low drive, but I also selected higher voltage FETs. Note the new wire: Flyback - connect this wire to the + side of your field to allow for the clamping diode to work.
