The Seeed Studio XIAO Series is a collection of thumb-sized, powerful microcontroller units (MCUs) tailor-made for space-conscious projects requiring high performance and wireless connectivity. Embodying the essence of popular hardware platforms such as ESP32, RP2040, nRF52840, and SAMD21, the Arduino-compatible XIAO series is the perfect toolset for you to embrace tiny machine learning (TinyML) on the Edge. The whole XIAO Series features compact design with all SMD components placed on the same side of the board, so designers can easily integrate XIAO into their boards for rapid mass production.
This repository is the official GitHub Project Hub for the XIAO Series, serving as an aggregated entry point for selection guidance, technical documentation, internal reference projects, and community-driven DIY works.

- Datasheets
- Schematic
- PCB design files
- PCB package libraries (including symbols)
- Pinout sheet
- 2D dimensional drawings
- 3D models
- Factory firmware
💡 Alternatively, you can refer to this comprehensive guide—arguably the most detailed selection guide in XIAO's history—Meet the Seeeduino XIAO Family, with special thanks to DroneBot Workshop for their contribution.
The XIAO Add-on are expansion modules and "hats" designed to enhance the functionality of XIAO dev boards. They cover a variety of applications including display, control, and sensing, and allow for quick prototyping without complex wiring.
XIAO Gadget is compact, application-ready hardware built with XIAO dev boards. By combining XIAO with sensors, displays, connectivity, and enclosure-friendly modules, XIAO Gadgets help makers and developers rapidly turn ideas into functional, real-world devices without complex custom hardware design.
Our team together with the community, has create a rich collection of wikis, applications and documentation. The Seeed Studio XIAO EXHIBITION page is organized as a centralized index to help developers quickly locate detailed tutorials, reference materials, and ecosystem support links for each XIAO development board. The page covers a wide range of topics, including:
- Product Guides
- Multiple programming languages and platforms
- Real-time operating systems (RTOS)
- Communication protocols
- TinyML and AI platforms
- Smart home solutions
- Open-source keyboard firmware support
- Other popular applications
- Prototyping tools (PCB Layout & Stimulation)
- IoT Clouds and IoT Platforms
If you are a beginner, we recommend starting with the Product Guides section to learn the fundamentals of XIAO hardware and basic protocol usage. From there, you can gradually move on to communication features and RTOS fundamentals, and finally explore advanced topics such as TinyML and AI, open-source keyboard firmware, and complete IoT system integration.
These projects are hands-on reproductions and validations of popular industry trends and real-world use cases, created by our internal engineers and shared in this repository’s projects folder. For each project, we include clear and practical step-by-step instructions in the project’s README.md file, so you can easily follow along and try it yourself. The projects currently available include:
- XIAO_ESP32-C3_BLE_ESPresense
- XIAO_ESP32_CSI_Espectre
- more coming soon…
