Operating on 3–6 V, it uses a PPM servo-style control method — forward, stop, and reverse are set by pulse width — eliminating the need for a separate motor driver.\n\nThe PH2.0-3P connector follows the Gravity pin standard for plug-and-play connection to DFRobot controllers and Arduino boards. With a 150:1 gear ratio and 133 RPM no-load output, it delivers reliable torque in a package weighing just 10 g.\n\nKey Features\n\n\nIntegrated Drive Chip – Single PWM signal controls speed and direction, no separate driver needed\n\nAll-Metal Gearbox – 150:1 reduction ratio for reliable torque output\n\nPPM Servo Control – Forward (500–1400 µs), stop (1400–1600 µs), reverse (1600–2500 µs)\n\nLow Standby Power – Less than 1 mA static current when no control signal is present\n\nGravity Connector – PH2.0-3P interface for easy plug-in connection\n\nCompact Size – 40 × 12 × 20 mm, weighing only 10 g\n\n\nSpecifications\n\n\nOperating Voltage – 3–6 V\n\nRated Voltage – 6 V\n\nNo-Load Current – 50 mA (at 6 V)\n\nStatic Current – <1 mA (no signal)\n\nStall Current – 640 mA\n\nMotor Speed (Unreduced) – 20,000 RPM\n\nGear Ratio – 150:1\n\nNo-Load Output Speed – 133 RPM\n\nStall Torque – 1.0 kg·cm\n\nPPM Signal Resolution – 1 µs\n\nPPM Pulse Width Range – 500–2500 µs\n\nPWM Drive Frequency – 500 Hz\n\nDimensions – 40 × 12 × 20 mm\n\nWeight – 10 g\n\n\nIdeal For\n\nRobotics and mechanical motion control\nValve and door lock actuators\nArduino and microcontroller projects\nCompact motorised mechanisms\n\n\nPackage Contents\n\n1× N20 Motor with Integrated Drive (133 RPM, 1:150)\n1× Gravity 3-Pin Digital Sensor Cable\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":543,"title":"Default Title","sku":"DF-DFR1114","mpn":"DFR1114","price":22.0,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":185,"option1":"Default Title"}]}
