Serial Bus Servo Driver Board 9-12.6V DC

The Serial Bus Servo Driver Board is a compact, powerful controller for controlling up to 253 ST/SC series bus servos in complex robotic systems. The board features USB and UART communication interfaces and acts as a central bridge between the host controller and the servo network. One core strength is bidirectional communication: the board not only sends commands but also reads real-time feedback on angle, load, and voltage of each individual servo. Through the software, individual IDs can be programmed for each servo and the operating mode can be switched between servo mode (position control) and motor mode (continuous rotation).
