Frequently asked questions
Which driver should I use with this motor?
Use a driver that supports 1.68A per phase and set the current at or below the motor rating, following the driver's datasheet. Common choices for this motor class include A4988, DRV8825 and TMC2209-class drivers.
How do I identify the coil wires among the four leads?
Use a multimeter in continuity mode. Wires belonging to the same coil show continuity with each other, so you can pair them as A+/A- and B+/B- before connecting them to the driver.
