Home Modules Sensor Arduino Raspberry Pi 3D Printer Chips Big Easy Driver board v1.2 A4988 stepper motor driver board 2A/phase 3D Printer Features: The Big Easy Driver, designed by Brian Schmalz, is a stepper motor driver board for bi-polar stepper motors up to 2A/phase. It is based on the Allegro A4988 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, a heatsink is recommended for loads approaching 2A/phase. You can find the recommended heatsink in the related items below. Note: The arrow indicators on the current adjustment potentiometer is backwards. Keep this in mind if you're adjusting the current limits. Note: This product is a collaboration with Brian Schmalz. A portion of each sales goes back to them for product support and continued development.
