An AB two-phase optical encoder designed for the DFRobot 2WD MiniQ robot chassis. Uses two infrared reflective sensors to generate quadrature pulse waveforms with approximately 90° phase difference, allowing you to determine both wheel speed and direction of rotation.

Mounts directly onto the motor bracket or mini robot chassis for PID speed control and position tracking. Works at 3.3 V or 5 V and connects via sensor cables for easy integration.

Key Features

• AB Two-Phase Output – Determines both speed and direction of rotation
