Building new pypilot motor controller

That is exciting news! 
Do you have access to a 12V diesel heater? That might provide a tester for inrush loads and steady state loads too. iirc, ~10A.

I don’t have access to a diesel heater at the moment, but I think the bulbs should work well. The cold filaments should provide a decent inrush current, and by switching multiple bulbs in parallel I can test a range of load levels.

I'm particularly interested in seeing how the board behaves thermally under sustained load—how much the MOSFETs and PCB heat up, and at what current level active cooling becomes beneficial or necessary. That should give a pretty good indication of the board's real-world operating limits.
