waveshare 30kg.cm@12V ST3215 Serial Bus Servo, High Precision and Torque, with Programmable 360 Degrees Magnetic Encoder, Two-Way Feedback, Servo/Motor Mode Switchable

• 【UART Serial Bus Control】Allows controlling up to 253 serial bus servos at the same time. 【Large Torque】Up To 30kg.cm torque on 12V voltage, suitable for building quadruped robots, hexapod walkers, robotic arms and other robotic projects requiring multiple servos. 【360° Magnetic Encoder,High Precision, Longer Lifetime】 Adopts 12-bit high-precision magnetic encoding angle sensor. Compared with the potentiometer, the angle is enlarged to 360°, and the resolution is increased by 4 times. Since there is a gap and no friction between the magnetic encoder and the radial magnet, the lifetime of the servo is effectively extended. 【Acceleration Start-stop Function】The speed and acceleration values can be set, and the motion effect is softer. 【One Button to Calibrate the Middle Position】360° installation at any position, one button to set the current position as middle position. Easy to install. 【Two-Way Feedback】The Servos will provide various feedback like position, load, speed, and input voltage in real time. 【Compact Structure Design】 The case adopts higher intensity engineering plastics, dual shaft and low profile design, shortening the plane spacing of the double-shaft servo wheel, and the overall structure is more compact, which can make the appearance of the product more beautiful. 【Application Examples】 Servos will provide various feedback like position, speed, torque lock, operating mode (servo mode, servo motor mode, etc.) for advanced projects requiring closed-loop automatic control. Ideal choice for building quadruped robots, hexapod walkers, robotic arms and other robotic projects requiring multiple servos. (This product provides the open source model of the quadruped robots as shown in the picture below.)
