Serial Bus Servo Driver Board (A) - Controller for ST SC Serial Bus Servos
Key Features:
- Allows controlling up to 253 ST/SC series servos simultaneously (sufficient power supply required)
- Wide input voltage range: 9V ~ 12.6V (must match the servo voltage)
- Supports communication via UART and USB Type-C port
- Can be connected to a PC host or microcontrollers (Arduino, STM32, ESP32, Raspberry Pi)
- Integrated control circuit ensuring stable operation of serial bus servos
- Compact dimensions and space-saving design – ideal for space-limited projects
- Two power supply methods: 5.5×2.1mm DC jack and screw terminal
UART and USB Control
The module allows easy switching of control modes (A or B) using a jumper. This enables quick prototyping with a computer via USB or integration with embedded systems via UART.
Compatibility with ST and SC Series Servos
The board supports ST and SC series servos. It enables reading feedback from servos such as position, speed, torque lock, or operating mode.
Note: It is not recommended to mix ST and SC series servos in one chain.
Wide Range of Applications
Ideal choice for building quadruped robots, hexapod walkers, robotic arms, and other projects requiring multiple motors in a closed-loop control system.
