Feature
Note:
We are introducing a new more durable packaging for all Seeed Studio XIAO boards (Un-Soldered, Pre-Soldered and Plus). During the transition period , you may receive XIAO boards in either the current or new packaging, while the product quality remains identical. Thanks for your understanding.

- Enhanced Connectivity: Combines 2.4GHz Wi-Fi 6 (802.11ax), Bluetooth 5(LE), and IEEE 802.15.4 radio connectivity, allowing you to apply the Thread and Zigbee protocols.
- Matter Native: Supports building Matter-compliant smart home projects thanks to its enhanced connectivity, achieving interoperability
- Security Encrypted on Chip: Powered by ESP32-C6, it brings enhanced encrypted-on-chip security to your smart home projects via secure boot, encryption, and Trusted Execution Environment (TEE)
- Outstanding RF performance: Has an on-board antenna with up to 80m BLE/Wi-Fi range, while reserving an interface for external UFL antenna
- Leveraging Power Consumption: Comes with 4 working modes, with the lowest being 15 μA in deep sleep mode, while also supporting lithium battery charge management.
- Dual RISC-V Processors: Incorporates two 32-bit RISC-V processors, with the high-performance processor running up to 160 MHz, and the low-power processor clocking up to 20 MHz
- Classic XIAO Designs: Remains the classic XIAO designs of the thumb-size form factor of 21 x 17.8mm, and single-sided mount, making it perfect for space-limited projects such as wearables
- Seamless integration with mainstream Cloud Platforms: ESP Rain Maker, AWS IoT, Microsoft Azure, and Google Cloud

Being the 8th member of the Seeed Studio XIAO family, XIAO ESP32C6 remains the classic XIAO design. All these features make it a perfect fit for either space-limited projects such as wearables, or a production-ready unit for your PCBA designs. (check out our Fusion one-stop prototyping and manufacturing services to explore what support you can get!).
Note
XIAO SoM User Manual open-sources all hardware and software materials of XIAO, providing professional product design guidelines to help you accelerate ideas off the ground, streamline product design, providing a seamless experience from module selection to mass production.

Starter Kit with free Course for all Electronics Neophytes and Enthusiasts
Seeed Studio has provided the Grove Starter Kit along with free and detailed courses for you quickly get started with microcontrollers and electronics, regarding all the Seeed Studio XIAO boards, promising you a great learning experience.
Not only programming but also electronics knowledge is not required, you will be taken step by step, from understanding the basic concepts to exercising the simple projects individually, finally being able to build complex, interesting, wearable projects on your own, owing a practical electronic product prototype from the course.
You can have access to the Seeed Studio Grove ecosystem by connecting it to the compatible Seeed Studio XIAO expansion board. We have developed more than 400 Grove modules, covering a wide range of applications that can fulfill various needs. For example, you can make a BLE AI-driven Smartwatch Detecting Potential Sun Damage by connecting the Seeed Studio XIAO nRF52840 with an expansion board, and a Grove - UV Sensor. Get started and explore the infinite possibilities of the Seeed Studio XIAO series!
If you are interested in programming embedded machine learning, we have Codecraft visual programming that can help you quickly start your own TinyML project. And we have set up a #tinyml channel on our Discord server, please click to join for 24/7 making, sharing, discussing, and helping each other out.
We already have 10 XIAO products based on different solutions in the XIAO family, to help you better understand the differences and choose the most suitable part for your projects, please refer to the Seeed Studio XIAO Series Page.
