I picked up a cheap Full bridge driver with the intent to use it as a unipolar stepper motor driver. (the one with 6 wires).
I am writing because I got the thing working, but the stepper motor is very jittery when I try to put it through full rotations and the current pull seems all over the place. I am trying various stepping scenarios with different delays between steps (averaging about 10ms), but like I said, its weird behavior.
I am wondering if its the Full bridge driver. The part number is TA8428K(S).
Thanks for your time,
