I like this board quite a bit for providing very flexible base capability. I’d like to hack in current sensing for both wheels independently, and it seems like the easiest way to do this is from the high side on VM motor supply pin for both DRV8838 drivers.
Is there a clean place to cut the traces ? I think i can see the traces from pin1 running to the center of board from both sides, but not entirely sure. A cutout section of gerber layers would help !
Any other suggestions to get current feedback from wheels also welcome.
In ideal world, the board could provide an optional traces with a jumper to get in there. Or even better, using a similar h-bridge with integrated current sense output, like DRV8871/3/4/6 or others.
