EasyDriver is microstepping motor driver based on the A3967 integrated circuit. It features  an on-board voltage regulator for the digital interface that can be set to 5 V or 3.3 V. This is compatible with any device that can output a digital 0 to 5 V pulse. MS1 and MS2 pins are routed out to change the microstepping resolution to full, half quarter, and eighth steps (default is eighth).
