The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse. EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor. Connect a 4-wire stepper motor and a microcontroller and you've got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors.
