EasyDriver - Stepper Motor Driver

The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). The EasyDriver requires a 6V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you致e got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors.
Features:
    A3967 Microstepping Driver
    MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)
    Compatible with 4, 6, and 8 wire stepper motors of any voltage
    Adjustable current control from 150mA/phase to 700mA/phase
    Power supply range from 6V to 30V. The higher the voltage, the higher the torque at high speeds
