PrintrBoard expansion pins, stepper driver?

I recently bought a PrintrBoard RevE which arrived with two burnt out stepper drivers (or at least one, the extruder does not seem to be working either, but not certain if that has to do with the temp etc)
If I were to get a pololu stepper board for example, could I wire that into the expansion pins of the printrboard?
If so, does anyone know where I could get an idea of the wiring and pins.h settings? Thanks much!
