Compatible Servos

Supports ST/SC series bus servos, and can directly power the servos via DC power jack, supports selecting power supply input according to the servo used

Note: It is NOT recommended to use ST series and SC series servos together. When using different models of the same series, pay attention to whether the power input can meet the requirements of all the servos at the same time.

UART serial bus control

Allows controlling up to 253 SC/ST series serial bus servos at the same time, supports receiving the operating status and various information feedback of each servo

Note: though one channel UART can control up to 253 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.
