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!
Those look great, I've been working on a much simpler design (more in my skill set), one for the pypilot and one for the motor controller using a VNH5019
Planning on having the pi zero w mounted on the underside of the board and the display/everything else on top in one of these cases: Case
Not cheap, but has a nice door to get inside.
Same case for this one too.
Ill be real interested to see yours when it works out.
