FEETECH ST-3215-C018 Servo Motor
The Feetech ST-3215-C018 is a high-torque 12V 30kg serial bus smart servo engineered for robotics, industrial equipment, and efficient small-torque drive application scenarios. Combining a lightweight plastic case with a durable metal gearbox and a reliable core motor, it integrates Feetech’s proprietary TTL control board with a 12-bit high-precision magnetic coding sensor. Delivering a powerful 30kg.cm stall torque, this intelligent servo provides 0-360° omnidirectional precise positioning, multi-turn continuous operation, one-key midpoint calibration, and programmable acceleration for smooth slow-start and slow-stop motion. Featuring comprehensive real-time telemetry feedback—including position, speed, voltage, current, temperature, and load parameters—the ST-3215-C018 ensures advanced overload and over-current protection for smart automation systems.
