28PA51G Optical Encoder DC Motor Module

This is a DFRobot custom-designed, high-quality DC motor featuring quiet operation and high torque output, with a built-in optical encoder. The optical encoder provides 663 pulses per revolution (PPR), offering an angular resolution of approximately 0.54° per step at the output shaft, which is sufficient to meet the requirements of general PID speed and position control. This motor is widely used in mobile robotics applications.
