Frequently asked questions
Which driver should I use with this motor?
Use a stepper driver such as the A4988 or DRV8825, or a compatible driver, and set its current limit according to the motor's rated current from the datasheet.
How do I identify the coil wires on the four leads?
Each coil uses a pair of wires. Use a multimeter in continuity or resistance mode to find the two pairs, then connect one pair to the A outputs and the other to the B outputs of the driver.
