Stepper Motor Driver DRV8825 Board

A DRV8825 on a breakout board, so you can drive a bipolar stepper motor from two microcontroller pins. Send a pulse on STEP and the motor moves one step; the level on DIR decides which way. Microstepping down to 1/32 of a step smooths out the motion, a trimmer sets the current limit to match your motor, and the chip protects itself against overcurrent, undervoltage and overheating.
