## Description

The Gravity N20 is a compact all-metal gear motor with an integrated drive chip that simplifies motor control to a single PWM signal. 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. The 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. Key Features Integrated Drive Chip – Single PWM signal controls speed and direction, no separate driver needed All-Metal Gearbox – 150:1 reduction ratio for reliable torque output PPM Servo Control – Forward (500–1400 µs), stop (1400–1600 µs), reverse (1600–2500 µs) Low Standby Power – Less than 1 mA static current when no control signal is present Gravity Connector – PH2.0-3P interface for easy plug-in connection Compact Size – 40 × 12 × 20 mm, weighing only 10 g Specifications Operating Voltage – 3–6 V Rated Voltage – 6 V No-Load Current – 50 mA (at 6 V) Static Current – <1 mA (no signal) Stall Current – 640 mA Motor Speed (Unreduced) – 20,000 RPM Gear Ratio – 150:1 No-Load Output Speed – 133 RPM Stall Torque – 1.0 kg·cm PPM Signal Resolution – 1 µs PPM Pulse Width Range – 500–2500 µs PWM Drive Frequency – 500 Hz Dimensions – 40 × 12 × 20 mm Weight – 10 g Ideal For Robotics and mechanical motion control Valve and door lock actuators Arduino and microcontroller projects Compact motorised mechanisms Package Contents 1× N20 Motor with Integrated Drive (133 RPM, 1:150) 1× Gravity 3-Pin Digital Sensor Cable
