This Driver is a simple board to use stepper motor, compatible with Arduino and other board that can output a digital 0 to 5V pulse or 0 to 3.3V pulse.
The Driver requires a 6V to 30V supply to power the motor and can power any voltage of stepper motor.
The boards drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors.

The microstep select (MS1 and MS2) pins and sleep and enable pins of the A3967 are broken out for further control.

Note: Do not connect or disconnect a motor while the driver is energized. This will cause permanent damage to the A3967 IC.
