FEETECH STS3020 Servo Motor, 7.4V 22.5kg.cm torque, 360° serial control, aluminium case, copper gears, 12-bit feedback

Overview

The FEETECH STS3020 Servo Motor (model STS3020-C001) is a serial-control actuator designed for robotics and automation. It operates across 5.5–14V and delivers a peak stall torque of 22.5kg.cm at 7.4V. The unit features an aluminium case, copper gear train, ball bearings, and a 12-bit magnetic-coded position sensor supporting 360° operation (when 0~4096). It communicates via half-duplex asynchronous serial using digital packet commands, with adjustable communication speeds from 38400bps to 1 Mbps and addressable IDs from 0 to 253. Integrated feedback includes load, position, speed, input voltage, and temperature.
