Adopts 12-bit high-precision magnetic encoding angle sensor. Compared with the carbon film potentiometer, the angle of the magnetic encoder 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.

Up To 30kg.Cm Torque On 12V Voltage, Suitable For Building Quadruped Robots, Hexapod Walkers, Robotic Arms And Other Robotic Projects Requiring Multiple Servos
![ST3235 Servo, with large torque, suitable for Robotic arms](/img/devkit/accessories/ST3235-Servo/ST3235-Servo-details-7.jpg)
Up to 253 serial bus servos controlling at the same time, with simple wiring, reducing the occupation of the serial port
![ST3235 Servo, with large torque, up to 253 serial bus servos controlling](/img/devkit/accessories/ST3235-Servo/ST3235-Servo-details-9.jpg)
Note: though one channel UART can control up to 253 serial bus servos, due to the high power of the servos, it is necessary to consider whether the power supply solution is enough when using too many servos. For reference only, the servo driver board is NOT included
The speed and acceleration values are settable to make the motion effect softer and reduce impact from inertia
360° installation at any position, one button to set the current position as middle position. Easy to install and debug
![ST3235 Servo, one button to calibrate the middle position step 1](/img/devkit/accessories/ST3235-Servo/ST3235-Servo-details-13-1.jpg)
1. Using the ST series demo we provided, a hotspot will be created automatically after the servo driver board is turned on. Use your mobile phone to connect to this hotspot, open the browser, and enter the IP address to enter the control interface.
2. Click Release to unlock, then turn the servo to the middle position where you need to set
3. Click Set Middle Position then confirm.
4. Turn the servo to any angle, then click Middle, and the servo will automatically return to the middle position initially set.
The Servo Will Provide Various Feedback Like Position, Load, Speed, Input Voltage, Current and Temperature In Real Time, with unloading force protection when the servo is overheated or overloaded

suitable for more application scenarios
Angle servo mode
Default mode, the angle position is controllable at 0~360° degrees
Speed closed-loop motor mode
Motor mode, intelligently control and maintain speed when the load changes
Step mode
Can perform step motion relative to the current position
Supports angle position control in both positive and negative directions up to 7 loops under the default precision setting, but the number of loops will not be saved in case of power loss. Lowering the angle resolution can double the number of control loops

Aluminum alloy case
Improves heat tolerance, structural strength, lifetime, and mechanical performance
![ST3235 Servo, built in high strength aluminum servo wheels](/img/devkit/accessories/ST3235-Servo/ST3235-Servo-details-21-2.jpg)
High strength aluminum servo wheels
Using T6061 aluminum alloy, good anti-corrosion performance
![ST3235 Servo, built in high precision copper and steel gears](/img/devkit/accessories/ST3235-Servo/ST3235-Servo-details-21-3.jpg)
High precision copper and steel gears
The combination of the two types of gears allows the servo to work with lower working noise, and enhances its stability and mechanical performance
