The Big Easy Driver, designed by Brian Schmalz, is a stepper motor driver board for bi-polar stepper motors up to 1.4A/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 about 1.4A 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 1.4A/phase.
