Frequently asked questions
Which driver should I use with it?
NEMA 17 motors are commonly driven by stepper drivers such as the A4988 or DRV8825. Set the driver current according to the motor's rated current, which should be verified before use.
How do I identify the wiring?
Most NEMA 17 motors have four leads forming two coils. Use a multimeter to find the two pairs of leads with resistance between them, and connect each pair to one driver coil output.
