UART Serial Bus Control
Allows controlling up to 253 serial bus servos at the same time
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
Easy to use, Large Torque
Supports 6.0~14V Wide range Voltage Input, And Can Be Directly Powered By 2S or 3S lithium batteries. Up To 25kg.Cm Torque On 12V Voltage, Suitable For Building Quadruped Robots, Hexapod Walkers, Robotic Arms And Other Robotic Projects Requiring Multiple Servos
Aluminum alloy middle case + Iron-core Motor + Metal Gear Box
Adopts high-reliability Design, suitable for industrial equipments, robotics, and other application scenarios that require angle or speed closed-loop control
360° Magnetic Encoder - High Precision, Longer Lifetime
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.
Acceleration Start-stop Function
The speed and acceleration values are settable to make the motion effect 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 and debug
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 confirm.
4. Turn the servo to any angle, then click Middle, and the servo will automatically return to the middle position initially set.
Two-Way Feedback
The Servo Will Provide Various Feedback Like Position, Load, Speed, Input Voltage, Current and Temperature In Real Time

Multiple operation modes 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
Multi-Loop angle Position control
Supports angle position control in both positive and negative directions up to 7.5 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
All-metal servo bracket
More Convenient to Develop the Structural Components, Combination Use More Flexible
Details Introduction
Aluminum alloy middle case
Improved heat tolerance, size stability, rigidity, and mechanical performance
High strength aluminum servo wheels
Using T6061 aluminum alloy, good anti-corrosion performance
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
All-metal bracket
More convenient to combine it with other devices
Open Source Control Program
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 project quickly.
