Big Easy Driver board v1.2 A4988 stepper motor driver board 2A/phase 3D Printer
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.
Features:
Bi-polar Microstepping Driver
2A/Phase Max
Max Motor Drive Voltage: 35V
On-board 5V/3.3V Regulation
