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.
Features:
Bi-polar Microstepping Driver
2A/Phase Max
Max Motor Drive Voltage: 35V
On-board 5V/3.3V Regulation

A4988 Red+Heat Sink
Simple step and direction control interface
Five different step resolutions: full-step, half-step, quarter-step, eighth-step, and sixteenth-step
Adjustable current control lets you set the maximum current output with a potentiometer,
which lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates
Intelligent chopping control that automatically selects the correct current decay mode
(fast decay or slow decay)
Over-temperature thermal shutdown, under-voltage lockout, and crossover-current protection
Short-to-ground and shorted-load protection
Warning:
Connecting or disconnecting a stepper motor while the driver is powered can destroy the driver.
(More generally, rewiring anything while it is powered is asking for trouble.)

The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse (or 0 to 3.3V pulse if you solder SJ2 closed on the EasyDriver). EasyDriver requires a 7V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V or 3.3V. Connect a 4-wire stepper motor and a microcontroller and you've got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire stepper motors. On this version (v4.4) we fixed the silk error on the min/max adjustment.
This is the newest version of EasyDriver V4 co-designed withBrian Schmalz. It provides much more flexibility and control over your stepper motor, when compared to older versions. The microstep select (MS1 and MS2) pins of the A3967 are broken out allowing adjustments to the microstepping resolution. The sleep and enable pins are also broken out for further control.
Note: Do not connect or disconnect a motor while the driver is energized. This will cause permanent damage to the A3967 IC.

Features:
A3967 microstepping driver
MS1 and MS2 pins broken out to change microstepping resolution to full, half, quarter and eighth steps (defaults to eighth)
Compatible with 4, 6, and 8 wire stepper motors of any voltage
Adjustable current control from 150mA/phase to 750mA/phase
Power supply range from 7V to 30V. The higher the voltage, the higher the torque at high speeds
