The ST3215-HS is a high-performance bus servo motor designed for advanced robotics applications. It features a 360-degree high-precision magnetic encoder and supports dual-mode operation, allowing it to function as either a standard servo or a continuous rotation motor. With a torque rating of 20kg.cm at 12V and a no-load speed of 106RPM, this unit is suitable for robotic arms, quadruped walkers, and automated systems requiring closed-loop feedback. The servo supports UART serial bus control, enabling the daisy-chaining of up to 253 motors on a single bus. It provides real-time feedback on position, load, speed, and input voltage for precise motion control.
