This geared DC motor comes with a built-in magnetic encoder — a magnetic wheel and two Hall effect sensors are already attached to the motor body, giving you quadrature feedback for both speed and direction without any extra wiring or mounting. It's the ideal starting point for closed-loop motor control in robotics projects.

Drive it at 7VDC via your motor driver, use PWM for speed and an H-bridge for direction control, and read encoder feedback directly into your microcontroller's interrupt pins to track RPM and rotation direction.
