{"title":"MiniQ Robot chassis Encoder","handle":"miniq-robot-chassis-encoder","url":"/products/miniq-robot-chassis-encoder","description":"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.\n\nMounts 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.\n\nKey Features\n\n\nAB Two-Phase Output – Determines both speed and direction of rotation\n\n12 Pulses Per Revolution – Infrared reflective sensing\n\n3.3 V or 5 V Operation – Dual voltage compatible\n\n<14 mA Current Draw – At 5 V\n\nAdjustable Sensitivity – Infrared receiver sensitivity tuneable via potentiometer\n\nCompatible Wheel Size – 42 × 19 mm (1.65\" × 0.75\")\n\nSensor Cable Interface – Easy plug-and-play connection\n\n\n\nNote: Infrared receiver sensitivity should be adjusted with an oscilloscope before use. To operate at 3.3 V, short resistor R4 on the board.\n\n\nIdeal For\n\nPID motor speed control on the MiniQ chassis\nWheel odometry and position tracking\nRobotics projects requiring directional feedback\n\n\nPackage Contents\n\n1× MiniQ Robot Chassis Encoder\n2× Sensor Cables\n\n\nResources\n\nWiki Documentation\nSchematic (PDF)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":10433,"title":"Default Title","sku":"DF-SEN0116","price":6.51,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":71,"option1":"Default Title"}]}
