I broke two A4988 breakout boards before purchasing this and it worked right away. Used it in conjunction with the DF Robot hybrid stepper. Works like a charm.

Great little board makes life easy
Takes all the pain out of driving steppers. Nicely designed, quality build, does what it says on the tin. Drives my six wire steppers just fine (just wire four of the six) - dead easy - set the direction line high or low and send a pulse for each step on the step line. The adjustable current limit lets you drive the motor from any voltage supply and just limits the max current per winding - in fact you get better results supplying with a voltage higher than the motor's rated voltage because then it has a bit more oomph to drive against any transient impedance, but still won't over-drive. Superb.
