The Big Easy Driver is a stepper motor driver 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 micro-stepping driver which defaults to 16 step micro-stepping 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 heat-sink is required for loads approaching 2A/phase. Features: Bi-polar Microstepping Driver 2A/Phase Max 1.4-1.7A/Phase w/o Heatsink Max Motor Drive Voltage: 30V On-board 5V/3.3V Regulation
