This bipolar stepper engines have been designed by ourselves. Unlike other steppers available out there, our design includes a 30cm length cable connector compatible with the vast majority of electronics, from RAMPS and Sanguinololu to Megatronics.

The engines provide a high torque with a nominal power of 10W.

The price is for one unit.
