The Bus Servo Driver Board supports ST and SC series servos with both UART and USB control. It includes a 2P 3.5mm screw terminal and integrates with the Seeed Studio XIAO ecosystem, providing precise, reliable control for robotic arms and multi-legged robot projects.


The Bus Servo Driver Board supports ST/SC series servos with UART and USB dual modes. It features a 2P 3.5mm screw terminal and is compatible with the Seeed XIAO ecosystem. Ideal for robotic arms and multi-legged robots using servos, it ensures rapid prototyping and precise control.

This expansion board is currently not directly compatible with the XIAO nRF54L15 series because Arduino is not supported. However, the hardware interface is fully compatible, and developers can manually adapt the software if needed. Official software support from Seeed Studio is under development — stay tuned for updates!

Features

  • Wide Compatibility: Supports ST/SC series serial bus servos, making it versatile for various robot projects.
  • Flexible Control: Offers UART and USB dual-mode communication, allowing easy control of multiple servos.
  • Professional Power Supply: Equipped with a 2P 3.5mm screw terminal for secure and reliable power connections.
  • Compact Design: Measures only 42mm x 25mm, ideal for integration into space-constrained projects.
  • Ecosystem Support: Seamlessly integrates with Seeed Studio XIAO series development boards for expanded functionality.

What is the Bus Servo Driver Board?

The Bus Servo Driver Board is a serial bus servo driver designed to manage and control servos operating on serial communication protocols (such as the ST/SC series). Through integrated control circuitry and communication interfaces, it converts user commands into servo actions, enabling coordinated multi-servo operation.

Unlike traditional PWM control, serial bus technology provides more efficient communication and greater scalability, making it particularly suited for robotics projects requiring multiple servos. This driver board offers both UART and USB control options, allowing users to choose between embedded system integration or convenient desktop debugging based on their needs.

Advantages of the Bus Servo Driver Board

Compared to other servo control solutions, the Bus Servo Driver Board stands out with distinct advantages. First, its compact 42mm x 25mm size and elegant design make it easy to integrate into space-constrained projects without compromising performance. Second, its dual-mode communication (UART and USB) balances real-time performance with ease of use—users can embed it into complex systems via UART or perform rapid debugging via USB, eliminating cumbersome wiring.

Additionally, it supports control of multiple servos with angle and load feedback, outperforming single-servo controllers in multi-degree-of-freedom applications. Paired with the Seeed Studio XIAO ecosystem, developers can quickly build feature-rich robotic systems, reducing the time from concept to prototype. Whether for education, research, or DIY creation, this driver board excels with its professional performance and user-friendliness.
