Description
Big Easy Stepper Motor Driver Board - SparkFun ROB-12859
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 bipolar stepper motor. It is a chopper micro-stepping driver which defaults to a 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 heatsink is required for loads approaching 2A/phase. You can find the recommended heatsink in the related items below.
Big Easy 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
