Product description: ST3235 30kg Serial Bus Servo - UART servo with 360 degree magnetic encoder - Waveshare 27166
The ST3235 from Waveshare is a high-end UART servo designed for advanced robotic projects. With an aluminum housing, reinforced steel gears and a non-contact 360-degree magnetic encoder , it offers long life and high control accuracy. It supports closed loop with current readings of position, voltage, temperature and load. It can operate in servo, motor or stepper mode , making it an extremely versatile solution for many applications. The servo can be easily configured and updated via the provided open source software. The input voltage ranges from 6 V to 12.6 V and the torque at a stopped shaft is 30 kg * cm / 12 V.
The manufacturer has also prepared a detailed user guide that significantly facilitates work with the servo.
ST3235 30kg Serial Bus Servo - UART servo with 360 degree magnetic encoder - Waveshare 27166.
The aluminum housing improves heat resistance and increases operational stability.
Main features of the servo
- High torque up to 30 kg*cm at 12V : ideal for complex structures requiring high force
- 360° multi-function magnetic encoder : increased accuracy (0.088°), frictionless and longer service life
- UART communication : supports up to 253 servos with one signal wire
- Closed control loop : real-time reading of position, voltage, temperature, speed and load
- CNC aluminum housing : heat resistant and mechanically strong
- Supports multiple operating modes : angle, motor and stepper mode with center position calibration
- Open source : fully compatible with Arduino IDE and Waveshare drivers
- Integrated acceleration/deceleration function : smoother movements and less mechanical stress
Practical applications
ST3235 is perfect for robotic projects requiring high precision and power . It can be used in robotic arms , quadruped robots (e.g. robotic dogs), humanoid structures, mobile carts, or complex manipulators. Thanks to closed-loop operation and multiple control modes, it is great for educational, research and industrial projects .
The servo provides a variety of feedback information, such as position, load, speed, and input voltage.
