  • I just wanted to let you know that I managed to drive a 4-phase 5-wire unipolar stepper using an easy driver. The connection is actually incredibly simple. Connect the four phase wires as you would with a bipolar motor (to the motor outputs on the EasyDriver chip) and then connect the 5th wire (COM) to the voltage supply (the same one driving the EasyDriver, i.e. M+).

No public wish lists :(
