Frequently asked questions
Which voltage should I use?
Use between 5 V and 7.2 V. The listing gives higher torque and speed at 7.2 V, and it should not be run above 7.2 V.
How is it wired?
The cable is 32 cm long. The listing does not give pin assignments, so confirm the lead colours and the control line for each axis in the product documentation before connecting it to a controller.
