Description
The UART serial bus servo is a two-way communication servo. User can customize the operation modes, feedback data, velocity control algorithms and protections. SDK is also provided to fulfill the development under various platforms.
Position Mode
The position is controlled in unit “degree” with a minimum step of 0.1º. No ADC converting needed.
Wheel Mode
Max no-load speed is 700º/sec. The number and time of the rotations can be set separately.
Locking Force Mode
While maintaining a certain output locking force, the angular position can be changed with external force.
Power Control
The maximum output power of the servo can be limited, and the current power data can be fed back in real time.
Velocity Control Algorithm
Provide smoother motion trajectory control during the servo start and brake phases.
Baud Rate Configuration
The baud rate can be modified from 9600-1Mbps to be compatible with different platforms.

Protocols
UART servos, each assigned with an ID at first, are connected in a bus channel. They communicate through a half-duplex asynchronous serial communication protocol. And the data can be exchanged with a full-duplex communication protocol through extension boards.
Physical Features
We strive to pursue the accuracy and reliability of every part in detail.
