Big Easy Driver V1.2 Stepper Motor Driver Board
Description: The Big Easy Driver£¬ designed by Brian Schmalz£¬ 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 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. 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
