FEETECH STS2000 Servo Motor
FEETECH STS2000 Servo Motor
The ST-2000-C001 is a high-precision 8.4V 24.3kg.cm TTL serial control servo designed for advanced robotics and automation systems. Constructed with an aluminum case, copper gears, ball bearings, and a core motor, this compact 62.1±1g unit delivers a peak stall torque of 24.3kg.cm and an idle current of 32mA at 8.4V, as well as a rated torque of 8.1kg.cm at 6V. It operates with a wide voltage range of 5.5V–9V, achieving a no-load speed of 68RPM (0.147sec/60°) at 8.4V. Featuring an unconstrained 360° running degree with no mechanical limits, the servo utilizes a 12-bit magnetic coding position sensor with a 4095-step resolution. Communication is handled via half-duplex asynchronous serial digital packets with an ID range of 0–253 and speeds from 38400bps to 1Mbps. The integrated telemetry provides comprehensive feedback on load, position, speed, input voltage, current, and temperature across an operating range of -10℃ to 60℃.
Common use cases: Compact humanoid robot arm and wrist joints requiring 12-bit magnetic encoder feedback, 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 across a wide 5.5–9V range.
