DJ,
I have an upcoming project using stepper motors and was wondering if you are implementing steppers into EZB? If so is it ready for prime time yet or anytime soon? Thanks in advance.

First is 5amp , second is 2amp but popular
I vote for the heavier stuff of course. After all, 2 amps is rather small.
Please let it be this one :

Please hurry DJ, I can hardly wait...
Best regards to all,

The Big Easy Stepper from Sparkfun and the A4988 Stepper Motor Driver Carrier from Pololu are real stepper controllers... Meaning they use industry standard step/direction 2 wire control, they have micro stepping if desired, but most importantly, they have current limiting. Current limiting lets you set how much current the motor coils get independent of voltage. Stepper motors are routinely run 10-20x their rated voltage via this method because it allows the motor to change position faster.
An EZ-B control for the Pololu A4988 will also work on a multitude of others, including Sparkfun's offerings, plus see TB6560 & 2M542 based controllers on eBay (stepper motor controllers/drivers for CNC routers).
