```\nST3215 19.5kg Serial Bus Servo 360°\n```

The Waveshare ST3215 is a precise serial bus servo for small to medium robotics and automation projects. With a torque of 19.5 kg·cm at 7.4 V operating voltage, it offers efficient performance at comparatively low supply voltage and is ideal for mobile robot platforms. An integrated 12-bit magnetic encoder enables absolute 360° positioning with 4096 steps of resolution. Unlike classic potentiometers, this encoder operates contactlessly, eliminating mechanical wear and significantly extending the servo's lifespan. Up to 253 servos can be daisy-chained and individually addressed via the serial UART interface. The ST3215 provides bidirectional real-time feedback on position, speed, load, and input voltage, and supports both a servo mode for precise position control and a motor mode for continuous rotation. The robust housing made of nylon-glass fiber composite material, the double-shaft construction, and high-quality metal gears ensure quiet, stable, and durable operation.
