About this part

The ST3215-HS is a high-speed serial bus servo for robot arms, quadruped walkers and other automated builds that need closed-loop feedback. It's controlled over a UART serial bus, so many servos can share one daisy-chained line, and each one reports its position, load, speed and input voltage back to the controller.

20 kg.cm torque at 12V, 106 RPM no-load speed
360-degree magnetic encoder with 4096 steps (0 to 4095) and no mechanical limit
Runs as a position servo or as a continuous rotation motor
Up to 253 servos on a single bus
Options: servo only, bracket only, or servo with bracket

Plan for a controller or adapter that can drive its UART serial bus.

Supplier description

Provided by the supplier. Our shipping, returns and support terms apply.

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.

Choosing a servo for robotics: SG90 vs MG90S vs MG996R vs serial bus servos

Compare SG90, MG90S, MG996R and serial bus servos by torque, size, gears and power, and work out how much torque a joint actually needs.
