The EasyDriver is an easy to use stepper motor driver, compatible with everything was capable of emitting a digital 0 to 5V pulse (or 0 to 3.3V pulse when you solder SJ2 closed to the EasyDriver). The EasyDriver requires a 30V to 6V supply to operate the motor and can supply any voltage of the stepper motor. The EasyDriver has an integrated voltage regulator for the digital interface, which can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you have precise motor control! EasyDriver drives bipolar motors, and motors are wired as bipolar motors. I.e. 4.6 or 8 wire stepper motors.
This EasyDriver V4.5 was developed in cooperation with Brian Schmalz. It offers much more flexibility and control over your stepper motor, compared to older versions. The micro-step selection pins (MS1 and MS2) of the A3967 have broken out, which allows the resolution of the microstep to be adjusted. The sleep and enable pins are also broken for further control.
