- 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.)

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.
The speed and acceleration values can be set, and the motion effect is softer
Actual Effect
Motion Effect Diagram
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.
360° installation at any position, one button to set the current position as middle position. Easy to install
1. In the default program, 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 comfirm.
4. Turn the servo to any angle, then click Middle, and the servo will automatically return to the middle position initially set.
The Servos Will Provide Various Feedback Like Position, Load, Speed,
And Input Voltage In Real Time

Nylon and fiberglass case
Improved heat-resistance, size stability, rigidity, and mechanical performance
High strength aluminum servo wheels
Using T6061 aluminum alloy, good corrosion-resistance
High precision copper and steel gears
Ingenious combination of the two, lower operating noise, better stability and mechanical performance
We provide the open-source web control demo of the servo driver board and a secondary development tutorial, which can be directly used for remote setting and remote control of the servo. At the same time, we also provide a 3D model for you to build your own project quickly
