XIAO Bus Servo Adapter

• ST/SC Servo Control by UART

Powered by XIAO ESP32-C3, you can directly drives ST/SC bus servos (require sufficient power) via UART while powering them with 512V through a robust 2P 3.5mm screw terminal, ensuring load-synchronized operation.

• Pocket-Sized Agility & Quick-Mount

Ultra-compact 42mm 25mm footprint with protruding side flanges featuring reinforced mounting holes, enabling rapid screw-based installation in embedded projects.

• Versatile Applications – Robotic Arm, Hexapod Robot, Humanoid Robot

Orchestrate complex kinematics like 6-DOF robotic arms, hexapods, or bipedal robots. Offers demo-ready compatibility with popular kits like the SO-ARM101 Low-Cost AI Armideal for AI vision projects and educational prototyping.

• Open-Source for Custom Development

Full Arduino IDE support enables bespoke motion programming, while the 3D-printed enclosure is open source, providing a starting point to customize your casing design.

FAQs

Q: How do I power the Bus Servo Driver Board?

A: Connect the power supply via the onboard 2P 3.5mm screw terminal. The input voltage range is 5-12V DC, which must match the rated voltage of the servos used and provide sufficient current to support all connected servos during operation.

Q: How do I connect servos and control devices to the board?

A: Servos are connected to the driver board via the 2.5mm 3P terminal, ensuring proper wiring (power, ground, signal lines). Control devices can be connected to a computer via the USB interface or to a microcontroller via the UART interface, with the specific mode determined by the jumper settings.

Q: How many servos can this driver board control?

A: It can control multiple ST/SC series serial bus servos, with the exact number depending on the power supply capacity and bus load conditions. Theoretically, it supports a large number of servos working together.

Note:If you’d like to control the bus servos via USB Type-C, you can purchase Bus Servo Driver Board for Seeed Studio XIAO!
