Thanks. I'm currently working on a PCB for my next version, and it'll have a voltage divider for current sense, ie, fix it in hardware. I'm just going to play with resistor values when I bring up the board.

I hope to be able to run stock motor controller code with no changes except for the VNH #define.
The red "dumbbell" shaped components are cuttable/solderable links to help me debug and alter the board. Fitting everything onto a 10x10cm PCB is a bit of a challenge!
