Description: The Big Easy Driver, designed by Brian Schmalz, is a stepper
motordriver board for bi-polar stepper motors up to a max 2A/phase. It is
based on the Allegro A4988 stepper driver chip. It’s the next version of the
popular Easy Driver board.
Each Big Easy Driver can drive up to a max of 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 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.
Note: This product is a collaboration with Brian Schmalz. A portion of
each sales goes back to him for product support and continued development.
