The stepper motor driver enables very precise control of the stepper motor. The DRV8825, located on this board, enables microstepping of a bipolar motor with an adjustable current limit, overcurrent and overtemperature protection. Controls steps up to 1/32 step. It has a potentiometer for setting the desired current.
