Each Big Easy Driver 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.

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 A4988 stepper driver chip. It’s the next version of the popular Easy Driver board.

It can take a maximum motor drive voltage of around 30V, 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 while operating at 1.4-1.7A/phase, a heatsink is required for loads approaching 2A/phase. You can find the recommended heatsink in the related items below.

  • Max Motor Drive Voltage: 30V
