- 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 5–12V 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 Arm—ideal 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!
