NEMA 11 Bipolar, 200 Steps, 28×32mm, 3.8V Stepper Motor - PL-1205
SY28STH32-0674A hybrid bipolar stepper motor has 1.8° step angle (200 step / revolution). Each phase draws 670 mA at 3.8 V, allowing a holding torque of 600 g-cm. The motor has four color-coded wires terminated with bare ends: black and green connect to a coil; red and blue are connected together. These leads are connected to the stepper motor via a removable JST-ZHR-5 connector. The motor can be controlled with a pair of suitable H-bridges (one for each coil), but bipolar
stepper motor driver.
