The Big Easy Driver is a stepper motor driver board for bipolar 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 bipolar 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 onboard 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 1.41.7A/phase a heatsink is required for loads approaching 2A/phase. Features: Bipolar Microstepping Driver 2A/Phase Max 1.41.7A/Phase w/o Heatsink Max Motor Drive Voltage: 30V Onboard 5V/3.3V Regulation
