The pin assignment of the mightyboard socket is flipped. You could use almost any other pololu-stepstick compatible driver IF you are able to solder the pins in reversed direction.
With the TMCs you might be in trouble with their large heatsink. You'd have to find longer pins. The microstepping is simple, just leave all the CFG-pins untouched and you are in stealthchop mode.
Also a DRV8825 would be better off being cooled from the bottom side ( which would be the top side when prepared for the mightyboard )
