The Waveshare Serial Bus Servo Control Board (Bus Servo Adapter A) is a compact and practical solution for controlling ST/SC series serial bus servos in robotics and automation projects. It combines the servo power supply and control circuitry on a single board, allowing a host computer or MCU to communicate with and control multiple bus servos through UART or USB Type-C.
With sufficient power, the board can theoretically control up to 253 serial bus servos while receiving useful feedback such as servo angle, load, voltage, and operating mode. Its compact 42 × 33 mm design makes it suitable for robotic arms, quadruped and hexapod robots, humanoid robots, wheeled robots, and other projects where multiple servos and feedback-based control are required.
