Choosing the right SoC for the next Seeed Studio XIAO is always challenging. It must represent cutting-edge technology, bringing innovation in communication networking, computing performance, or ecosystem compatibility. When Silicon Labs EFR32MG24 came into our view, we were immediately excited by its enormous potential to make the promising Matter® wireless communication protocol accessible to ALL – perfectly aligning with Seeed’s vision of Making Technology Accessible for ALL.

Matter connects IoT platforms and smart home devices across different brands, bridging the gap between different ecosystems like Amazon, Google, and Apple. This new industry-unifying standard provides reliable connections and simplifies development for makers. We are now thrilled to introduce the Seeed Studio XIAO MG24 and the Seeed Studio XIAO MG24 Sense, thumb-sized Matter®-native dev boards all powered by Silicon Labs EFR32MG24!

Seeed Studio XIAO MG24 (Sense), Tailored for Battery-Powered Matter Applications

The Seeed Studio XIAO MG24 and XIAO MG24 Sense are two tiny Arduino-compatible development boards that uniquely combine Matter with the Seeed Studio XIAO ecosystem. The EFR32MG24 Wireless SoC features a 32-bit ARM Cortex-M33 core processor running at 78MHz with DSP instructions, 1536KB Flash memory, and 256KB RAM. Thanks to the Silicon Labs SoC inside, the XIAO MG24 and XIAO MG24 Sense support Matter® over Thread® and Bluetooth® Low Energy 5.3. In the future, there will be support for the other common 2.4 GHz protocols on the Arduino Core.

In the signature Seeed Studio XIAO form factor (21×17.8mm), both XIAO MG24 and XIAO MG24 Sense feature 4MB onboard Flash capacity, LED, and 19 GPIOs. The XIAO MG24 Sense additionally includes two onboard sensors: an analog microphone and a 6-axis Inertial Measurement Unit (IMU). These new XIAO boards excel in battery management, featuring an onboard charging circuit, internal IO for battery voltage measurement, and support for an increased charging current of 160mA. Their battery management system and ultra-low-power consumption design make them ideal for the rapid development and prototyping of Matter-based battery-powered IoT devices.

“Seeed Studio has consistently delivered innovative and cost-effective hardware solutions that empower developers around the globe. We are thrilled to collaborate with them on the XIAO MG24 boards, which integrate our EFR32MG24B220F1536IM48-B chip. This partnership not only broadens the reach of our technology but also aligns with our vision of fostering a vibrant developer community. We look forward to seeing the creative and impactful applications that will emerge from this collaboration,” says Rob Shane, Vice President, Mass Market Sales & Applications at Silicon Labs.

Seeed Studio XIAO for Matter: XIAO MG24 (Sense) & XIAO ESP32C6

These aren’t our first Matter-compatible XIAOs. Earlier this year, we launched the XIAO ESP32C6, supporting multiple protocols including Zigbee, Wi-Fi 6, BLE 5, and Thread. For those wondering about the differences between these models, please refer to the comparison table below to find the perfect match for your Matter applications.
