By: Lily

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.

XIAO MG24 Sense Hardware Overview

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.

Join Our Seeed Studio XIAO Early Adopter Program

XIAO MG24 and XIAO MG24 Sense are now available for pre-order through our Bazaar webstore at $7.9 and $10.9 respectively, with shipping expected in late November 2024. To celebrate the launch, here is a limited-time offer: 10% off for the first 100 purchases. Shop NOW.👇

To help developers quickly adapt their projects to the XIAO MG24 (Sense), we’re launching our XIAO Early Adopter Program. If you’re an author or maintainer of a popular open-source Matter or IoT project on GitHub, or an influencer on YouTube, TikTok, or Instagram, ensure your users can run your code on the XIAO MG24. Join to receive two free early sample boards (shipping mid-November) and technical support for making your code compatible with this exciting new board.

SONOFF ZBMINIR2 review – A mini Zigbee switch & Zigbee router tested with eWeLink and Home Assistant

Sonoff ZBMiniR2 Cover

We have received another Zigbee device from SONOFF for review, namely the ZBMINIR2 which we’ll review with both eWelink adn Home Assistant. Many people may be familiar with the first-generation mini Zigbee Switch that SONOFF released in 2020, known as the ZBMINI. ZBMINI was one of the early Zigbee Switch models, which also acted as a Zigbee Router. The ZBMINIR2 is SONOFF’s second-generation mini Zigbee Switch including both software and hardware upgrades compared to its predecessor. Improvements include a smaller size, better signal quality, an increase in the number of supported devices (2x), wider coverage (5x), and additional features. Let’s dive into the details. Unboxing ZBMINIR2 Zigbee switch Inside the box, you’ll find a small user manual and the ZBMINIR2 device as usual. It is notably smaller than the predecessor model, which makes installation much easier in many cases. For example, it can now fit into the wall box behind [...]

Arduino Nano Matter powered gamepad runs Quake at 27 FPS

Arduino Nano Matter gamepad board

Silicon Labs Solutions architect Nicola Wrachien has designed an Arduino Nano Matter gamepad for which he was successfully able to port Quake, a popular first-person shooter game. We have seen developers and engineers port doom on everything from toothbrushes to GPS receivers. Wrachien was previously able to port Doom on a Sparkfun Thing Plus Matter MGM240P at Silicon Labs’ 30th-anniversary celebration. But to make things more interesting and challenging he wanted to see if Quake could be run on the same MGM240SD22VNA MCU, and he succeeded. In the end, he could not only run the game, but he also implemented improved graphics (better than Doom), better physics, 3D rendering, and much more. This gamepad is built around an Arduino Nano Matter board which features MGM240SD22VNA MCU from Silicon Labs, along with 256KB of RAM, which is very low compared to Quake’s original system requirements which is a minimum of 8MB [...]

SONOFF ZBMINIR2

SONOFF ZBMINIR2 is a tiny Zigbee smart switch that looks very similar to the SONOFF Zigbee Extreme (ZBMINIL2) but requires a neutral wire and can act as a Zigbee router with up to 64 sub-devices. It also supports new features such as “Turbo mode” for extended range and “detach relay” mode where the states of external switches and relay are separated, so operating the external switch button won’t affect the relay state. The tiny wireless switch can fit into the smallest EU-type/86-type/120-type mounting boxes and works with gateways supporting the Zigbee 3.0 protocol such as ZBBridge Pro, NSPanel Pro, and other compatible Zigbee 3.0 hubs. It also supports external switches (momentary, door, SPDT, and rocker), voice control through Amazon Alexa and Google Home, and like other SONOFF devices is designed to be controlled through the eWelink mobile app by default. SONOFF ZBMINIR2 specifications: MCU – Unspecified – Potentially the same [...]
