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
- 12 Pulses Per Revolution – Infrared reflective sensing
- 3.3 V or 5 V Operation – Dual voltage compatible
- <14 mA Current Draw – At 5 V
- Adjustable Sensitivity – Infrared receiver sensitivity tuneable via potentiometer
- Compatible Wheel Size – 42 × 19 mm (1.65" × 0.75")
- Sensor Cable Interface – Easy plug-and-play connection
Ideal For
- PID motor speed control on the MiniQ chassis
- Wheel odometry and position tracking
- Robotics projects requiring directional feedback
Package Contents
- 1× MiniQ Robot Chassis Encoder
- 2× Sensor Cables

Jargon buster
Plain-language definitions for the technical terms used above.
- encoder
- A device attached to a motor or shaft that reports movement, such as rotation steps or position. In a pump system, an encoder can help measure or control how much the motor has turned, which affects how repeatable the watering amount can be.
- potentiometer
- A variable resistor usually turned with a knob or shaft to create an adjustable electrical signal. It is often used for inputs such as volume, brightness or position, so it helps beginners learn how a microcontroller reads changing values.
