Big Easy Stepper Driver

The Big Easy Driver, designed by Brian Schmalz, is a stepper motor driver board for bi-polar stepper motors up to 2A/phase. It is based on the Allegro A4983 stepper driver chip. It's the next version of the popular Easy Driver board.

Each BigEasyDriver can drive up to about 2A per phase of a bi-polar stepper motor. It is a chopper microstepping driver which defaults to 16 step microstepping mode. It can take a maximum motor drive voltage of around 35V, and includes on-board 5V/3.3V regulation, so only one supply is necessary. Although this board should be able to run most systems without active cooling, a heatsink is recommended for loads approaching 2A/phase.

Note: This product is a collaboration with Brian Schmalz. A portion of each sales goes back to them for product support and continued development.

  • Bi-polar Microstepping Driver
