FEETECH STS3215 Serial Bus Servo

Product Overview

This FEETECH STS3215 serial bus servo is a high-performance robotic actuator specially designed for SO-ARM100/101 robotic arms. It features full-dimensional real-time feedback, metal gear transmission, magnetic encoding sensor, and standard TTL serial bus communication, with multiple intelligent protection mechanisms built-in. It natively supports ACT, Smolvla, Pi0, Pi0.5, GR00T N1.5 robot model training, making it ideal for robotic development, embodied intelligence research, and educational robotics scenarios. Official invoice support available for all orders.

Key Advantages

  • Native Compatibility with SO-ARM Series Robotic Arms

    Perfectly adapted to SO-ARM100 and SO-ARM101 robotic arms, works out of the box after simple configuration, saves development time for robotic project integration.

  • Full-Dimensional Real-Time Feedback

    Supports real-time feedback of position, speed, torque, temperature, and voltage data, providing reliable data support for closed-loop control and precise motion development.

  • High-Reliability Hardware Design

    Adopts high-precision metal gear transmission structure and non-contact magnetic encoding sensor, with high durability, low noise, stable operation performance, suitable for long-term continuous operation scenarios.

  • Supports Mainstream Robot Model Training

    Fully compatible with ACT, Smolvla, Pi0, Pi0.5, GR00T N1.5 and other mainstream robotic large model training frameworks, meeting the needs of embodied intelligence model training and development scenarios.

  • Multiple Intelligent Protection Mechanisms

    Built-in overvoltage, overcurrent, overheating, overload and other intelligent protection functions, effectively protecting the servo and connected equipment from damage, improving the stability of the entire robotic system.

  • Standard TTL Serial Bus Communication

    Adopts standard TTL serial bus protocol, supports multi-servo cascade connection, simplifies system wiring and reduces development difficulty.
