Andrew,
I have the Little Step U and love it, however it's a 1:1 ratio. Sorry.

Just a quick newbie question regarding the little step-u...
Is it pretty much a 1:1 ratio to # of little step-u's to # of stepper
motors? Or is there a clever way to wire up a little step-u to run
more than one stepper motor independently. The reason why I ask is
because I am designing something that operates similar to a plotter
and need to know if one step-u can run both x and y. Thanks!
Andrew

circuit and software for controlling a stepper with only 2 stamp pins.
It uses a ULN2003 Darlington driver chip to handle the switching logic.
I added a 2nd ULN2003 for controlling a 2nd stepper simultaneously, and
it works well for driving 2 steppers with 4 stamp pins. I added a relay
for ON/OFF control of the motor voltage. As shown, the Parallax circuit
leaves the motors always ON.
