DFRobot Stepper motor Nema 17 42x42mm 1.75Nm with planetary gearbox

This bipolar stepper motor with planetary gearbox (gear ratio: 5.18:1) features a D-type output shaft with a standard diameter of 8 mm and has a step angle of 1.8° (200 steps/revolution). Each phase draws 1.0 A at 3.4 V and provides a holding torque of 18 kg/cm or 176 Ncm. The motor can be easily mounted using the four M3 threaded holes. For controlling the stepper motor with Arduino, I recommend using a stepper motor driver such as the DRV8825 or even better, the TB6600.
