Frequently asked questions
Which driver do I need for this motor?
A two-phase stepper driver such as the A4988 or DRV8825 works with this motor. The rated current is not clearly stated in this listing description, so confirm it in the datasheet before setting the driver current limit.
How do I connect the Dupont leads?
The four-lead cable forms two coils with two wires each. Find the coil pairs with a multimeter continuity test, then connect them to the A and B outputs of the driver. If the motor turns the wrong way, swap the polarity of one coil.
