For wiring up the stepper drivers A = Black, B = Green, C = Red, D = Blue

Just to clarify, the Stepper Driver 2.3 does work with the FL42STH38-1206A Tried and Tested. (Leave center taps for the coils unconnected) However if your stepper is a 5-Wire Unipolar stepper, your mileage may vary

You may have one problem, but on the positive side you can use much cheaper driver circuits for unipolar motors. In addition you can make a much cheaper circuit that is able to supply higher currents to the motors than many driver circuits you get for bipolar motors.

I don’t know how you could wire up a 5-wire unipolar stepper to work with a Stepper Driver 2.3 but there is a simple circuit here that might be suitable depending on your load requirements http://arduino.cc/en/Reference/StepperUnipolarCircuit

This is kinda what makes steppers a pain in the butt, I have 2 smaller ones I would like to use but they are the 5 wire unipolar ones. I still do need to find another stepper motor though.
