FEETECH STS3020 Servo Motor

The ST-3020-C001 is a high-performance 8.4V 24.3kg.cm TTL serial control servo featuring a robust aluminum case, copper gears, and durable ball bearings. Driven by a core motor, this no-limit servo delivers a peak stall torque of 24.3kg.cm at 8.4V (rated torque of 8.1kg.cm at 6V) and a no-load speed of 0.147sec/60° (68RPM) with a 2.6A stall current. Operating within a 5.5V–14V voltage range, it utilizes half-duplex asynchronous serial communication supporting an ID range of 0–253 and communication speeds from 38400bps to 1Mbps. Designed for precise 360° rotation (0–4095 steps), its integrated 12-bit magnetic coding position sensor provides comprehensive real-time feedback on load, position, speed, input voltage, current, and temperature. Compact and reliable, the servo measures 40.2mm × 20.2mm × 40mm, weighs 61.7±1g, and features a 25T/OD5.9mm horn gear spline with a 15CM PH2.0-3P connector wire.

Common use cases: Compact humanoid robot arm and wrist joints requiring 12-bit magnetic encoder feedback with wide 5.5–14V voltage compatibility, educational robot platforms with TTL serial BUS daisy-chain wiring, lightweight RC models needing serial BUS control, and applications requiring 24.3kg.cm torque in a 62g package with full telemetry.
