This micro stepper motor (20mm square) of 200 steps/revolution (i.e. a 1.8° step angle) has a weight of 60 g. It uses 3.9V at 600mA to create a torque of 180 g-cm. The 4mm diameter D-shaft has been flattened by 0.5mm. This bipolar stepper motor has four color-coded wires terminated with bare leads: black and green connect to one coil; red and blue connect to the other. It can be controlled by a pair of suitable H-bridges (one for each coil), but we recommend using a bipolar stepper motor driver.
