Feetech STS3215 Bus Servo 7.4V 19.5kg.cm (LeRobot)

Feetech STS3215 Bus Servo 7.4V 19.5kg.cm (LeRobot)

🤖 The servo that powers the open-source robot-arm revolution.

🔍 Product Overview

The Feetech STS3215 is the smart serial-bus servo at the heart of the LeRobot SO-100 and SO-101 arms. Its 12-bit magnetic encoder delivers far better positional accuracy than potentiometer hobby servos - critical for clean imitation-learning data - and its TTL serial bus lets you daisy-chain many servos on one line for tidy multi-joint wiring. Metal gears, position/velocity/current/temperature feedback, 360-degree control.

📋 Technical Specifications

🧩 Purpose & Real-World Applications

• LeRobot SO-100 / SO-101 arm builds - the exact servo these open-source arms use

• Bus-servo robots - hexapods, snake robots, grippers, pan-tilt heads

• Repairs & spares - replace worn servos in existing arms

• Custom robotics - daisy-chained TTL bus keeps wiring simple in multi-joint builds

🎯 Who Is This For?

Robotics engineers, AI startups and students building or maintaining LeRobot arms and bus-servo robots - buy singly or in bulk for full builds.
