Stepper Motor Driver (2A - Big Easy Driver)
The Big Easy Driver 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.
Note: The arrow indicators on the current adjustment potentiometer is backwards. Keep this in mind if you're adjusting the current limits.
