I really like the stepper drives from UIrobot, see http://en.uirobot.com/robot-product.html
They are nice tiny, you can mount it direct to the stepper, heatsink is included and you do not need a special box for the motor dirver.
I have contacted the support of UIrobot and they mentioned to use model UIM24002, UIM24004 or UIM24008 for an Arduino project. Unfortunatelly I coudn't found any circuits or example code for the UIrobot driver. So I hope I can use the standard stepper library and code, see: http://arduino.cc/en/Reference/Stepper
or do I have to use a complete other approach?
You have -- beside power -- only this wiring inputs:
DIR Direction input
STEP Stepping pulse input
EN Enable the controller
Is there any exampe code and circuit for Arduino and UIrobot driver?
I really love the form factor of this dirver, really unique and a nice "one thing" with no extra enclosure. Would be great if you have some best practice examples how to handle it with an Arduino.
