Would this micro Controller-Driver work? OO gauge TTTE Breakdown Crane
Im trying to make an RC controlled oo-gauge breakdown crane where all the electronics, battery and at least 1 motor have to live in the same 40x35x35mm cab. I've done all the research I can alone, but do people think this would work? I need 3 motors driven, so finicky work getting 2 H drivers on there for a fat fingered solderer, but with a spare board or two I think I could manage
SEED Xiao-C3
DRV8833 (x2)
EEMB 3.7V 1800mAh 963450 Lipo
6mm Planetary motors (x3)
Points of note:
- Battery pads will be soldered to lipo and routed through DRV8833 HDrivers. Will the H drivers drain the battery when not in use (AKA Where would I put the power switch, surely I I break the ground/live it wont charge when 'powered off' or is that just the sacrifice Im making to make it this small)
- Planning to drive this off a phone to reduce price/building of a reciever, whats the best software to load of custom code on a iPhone/android (cross compatibility would be grand in case someone else wants to play with it)
- Is there just a premade package that just already does this, I tried buying a tiny RC digger that nearly had the three motor outputs, but two of the motors are driven together and seem, hardcoded into the board
Thank you for looking!
