Description
Description: The Big Easy Driver, designed by Brian Schmalz, is a stepper 
motordriver 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
