Pcb with motor breakout made it in a couple days early.

Clearance is spot on but might want a heatsink. Thinking about pin options.

Ld293D Motor driver has 2 channels @600ma but takes 4 digis + 2 pwms on the enable pins.

Its the same ic from the original Motor Shield, not much current but high motor voltage.

I think I will print a Test stand arm to try to measure thrust and test Steering...
