Modify unipolar stepper motor to bipolar
I followed a
on how to modify this unipolar stepper to be bipolar, because BeagleBone Blue has built-in H-bridges.
I used an EduMIP, which has DC motors on M2 and M3, so I grabbed M1 and M4.
I used a wiring housing to line up the wires to the stepper motor header.
- M1+: Pink (2)
- M1-: Orange (4)
- M4+: Yellow (3)
- M4-: Blue (1)
- center-tap (unused): Red (5)
