## Description

The Bus Servo Adapter (A) is a compact driver board that integrates power supply and control circuitry for ST/SC series serial bus servos. It supports controlling up to 253 servos simultaneously over a single UART channel, with position, speed, torque, and operating mode feedback from each servo. The board offers both USB and UART control modes, selectable via an onboard jumper. USB mode allows direct connection to a PC, Raspberry Pi, or Jetson for quick prototyping, while UART mode enables integration with Arduino, ESP32, STM32, and other microcontroller platforms. Key Features Up to 253 Servos – Control multiple ST/SC series bus servos on one UART channel Dual Control Modes – USB or UART, selectable via jumper Integrated Power Circuit – Powers servos directly via DC jack or screw terminal Servo Feedback – Position, speed, torque lock, and operating mode data Compact Form Factor – Suitable for space-limited projects Multi-Platform SDK – Compatible with Raspberry Pi, Jetson, ESP32, Arduino, STM32 Specifications Input Voltage – 9–12.6V DC (must match servo voltage requirements) Power Input – DC 5.5×2.1mm jack or screw terminal USB – USB Type-C connector Control Interface – UART or USB (jumper selectable) Compatible Servos – ST and SC series serial bus servos Ideal For Quadruped and hexapod robots Robotic arms and grippers Multi-servo projects requiring closed-loop control Rapid servo prototyping via USB Package Contents 1× Bus Servo Adapter (A) Note: It is not recommended to use ST series and SC series servos together. When using different models of the same series, ensure the power supply can meet the requirements of all connected servos simultaneously. Resources Waveshare Wiki
