The Big Easy Driver is a simple solution using an Allegro A4988 IC for driving a single bipolar stepper motor at up to 2A/phase to maximum 35V.


Additional Information [Hide]

With all the 3D printers and other projects sprouting up on the internet, it's good to know there's some easy ways to drive that stepper motor you salvaged out of the old office copier.

The Big Easy Driver uses the Allegro A4988 IC to push up to 2A per coil @ 35V through your motor, and includes onboard 5V/3.3V regulation so you don't have to worry about running logic power to each board. But be warned: Motor coils must be connected before wiring up, or you risk letting out the magic smoke! And running close to the 2A maximum does require additional cooling or additional heat-sinks. Also, the Vcc pin on the board is an OUTPUT, not input.

  • Bi-polar Microstepping Driver
