This is a simple 2-phase hybrid stepper motor. It is characterized by a high torque of 3.5 kg. It is used in most CNC machines or 3D printers such as Makerbot and Ultimaker. If you want to make your own CNC or 3D printer, this motor is the most suitable. Normally a CNC machine requires 3 motors and a 3D printer even 4.

This motor has been continuously tested by DFRobot Lab for 3 months. After testing more than 10 different stepper motors, they finally have one that meets their quality and price requirements.
The motor comes with a 4-pin JST connector that is compatible with the Ultimaker Control Board.
