Seeed Studio Xiao - Project Board

Technical Documentation: GitHub
Video Overview: coming soon!

This project board is designed to work with the Seeed Studio Xiao Series Development Boards

The AP-XIAO-PB-3V3-V1 cuts down on wiring headaches and power supply hacks, giving you clean voltage rails, level shifting, and flexible outputs right out of the box. Whether you’re prototyping or building a permanent project, this board helps you get from idea to working build faster.

Key Features

• USB-C Power Delivery: When powered via USB-C, this board will request a 12v PD Profile. If the Charger does not have that power profile, it will drop to an input of 9V. See technical docs for more information.
• Multiple Voltage Rails: Vin, 5V, and 3.3V available at your fingertips. Power your ESP32-S3, sensors, and modules with ease.
• Integrated Level Shifter: Seamlessly connect 3.3V and 5V devices without worrying about damaging your microcontroller.
• N-Channel MOSFET Control: Use PWM to control two-wire motors, fans, or other devices. Adjust speed and power smoothly without extra hardware.
• Designed for Reusability: Perfect for both quick experiments and long-term installations.

Most DIY projects stall on wiring, power conversion, and pin compatibility. This board handles those pain points so you can focus on building, not troubleshooting.
