Done a lot of looking on the forum and still can't figure it out. I am building a pretty heavy duty robot and want to use the power of stepper motors. Question is - how do I interface the stepper motor with the EZB? I have Kollmoren P22 stepper motor - 8 wires, capable of bipolar, unipolar and parallel operation. I guess I need a recommended drive shield board and then how do I hook that to the EZB? I am expecting to need to drive up to 4 of these motors.
