Application Examples
  • Servo motor will provide various feedback like position, speed, torque lock, working mode (servo mode, servo motor mode, etc.) for advanced projects requiring closed-loop automatic control.
  • Ideal choice for building wheeled robots, 3D printers, etc. that require accurate closed-loop speed control or stepping control; it can also be used for building quadruped robots, hexapod walkers, robotic arms and other robotic projects requiring multiple servo motors. (This product provides the open source model of the quadruped robots as shown in the picture below.)

UART Serial Bus Control

Allows controlling up to 253 bus servo motors at the same time

Note: though one channel UART is able to control up to 253 bus servo motors, due to the high power of the servo motors, it is necessary to consider whether the power supply solution is enough when using too many servo motors. For reference only, the servo driver board is NOT included

Large Torque, High Speed

Up To 20kg.cm Torque On 12V Voltage, Suitable For Building Quadruped Robots,
Hexapod Walkers, Robotic Arms And Other Robotic Projects Requiring Multiple servo
motors with large torque and high speed performance

Supports installing flat key shaft flange

With the flat key shaft flange designed for the serial bus servo, it is possible
to drive various transmission parts

* for reference only, the flat key shaft flange and wheels are Not included.

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 motor is effectively extended.

Acceleration Start-stop Function

The speed and acceleration values are settable to make the motion effect softer

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.

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

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 motor to the middle position where you need to set

3. Click Set Middle Position then comfirm.

4. Turn the servo motor to any angle, then click Middle, and the servo motor will automatically return to the middle position initially set.

Two-Way Feedback

The Servo Motor Will Provide Various Feedback Like Position, Load, Speed,
And Input Voltage In Real Time
