Our Seeed Studio XIAO ecosystem has been growing steadily with tap-on accessories like Grove Expansion Boards, Sensors, Connectivity Modules, and Actuators to complement our thumb-sized dev boards. But one thing kept coming up in our XIAO Open Roadmap – you wanted more relays! Well, we heard you, and here’s our answer: the new Seeed Studio 2-Channel AC Wi-Fi Relay.

Powered by our thumb-sized XIAO ESP32C3, this Home Assistant-native relay device lets you control two independent 100-240V AC loads – perfect for lights, appliances, and motorized facilities. We’ve pre-flashed it with ESPHome firmware and built in a power meter, so you can track both real-time and historical power consumption right from your Home Assistant dashboard. 

All the above-mentioned features make it particularly suited for applications that need both remote control and power monitoring of household electrical devices through a smart home automation system.

Want to know what’s under the hood? We’ve packed in two 10A/250VAC high-power latching relays (HF3F-L), giving you control over two loads on a 50-60 Hz AC carrier signal. Here’s a sneak peek at the internals – and don’t worry, we’ll be open-sourcing all schematics on our Wiki soon!

Ready to get your hands on one? The Seeed Studio 2-Channel AC Wi-Fi Relay is available for pre-order at our Bazaar webstore for just $19.90. Shipping starts in early January 2025, and it’ll also be available on our AliExpress and Amazon stores.

Oh, and one more thing! The relay comes in a white 3D-printed enclosure (which you can download and customize from Thingiverse for free). And for all you makers and developers who want to DIY with your existing XIAO boards – stay tuned! We’re working on a universal Relay Add-on that’ll be compatible with all XIAO dev boards.

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.

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.

Millimeter Wave (mmWave) radar technology, recognized for its high accuracy, privacy-centric capabilities, adaptability, and flexibility, is increasingly becoming a critical tool in privacy-oriented sensing applications. These applications range from presence and fall detection to sensitive monitoring of breathing and heartbeat.

To empower developers worldwide to adapt mmWave radar for more responsive automation, we are now excited to introduce two new mmWave Sensor Kits designed to meet diverse needs:

• MR60BFD2 60GHz mmWave Fall Detection Sensor Kit with XIAO ESP32C6

• MR60BHA2 60GHz mmWave Breathing and Heartbeat Detection Sensor Kit with XIAO ESP32C6

Priced at $24.9, both kits utilize the same hardware platform but are equipped with specialized pre-set algorithms tailored for distinct motion detection tasks—fall detection and breathing & heartbeat monitoring, respectively.

Key Features of the New mmWave Sensor Kits

These kits leverage 60GHz mmWave technology to offer reliable detection capabilities:

• Presence and Fall Detection: Detects subtle motions, accurately identifying human activities such as standing, walking, or falling.

• Presence, Breathing and Heartbeat Monitoring: Captures minute displacements caused by heartbeat and chest movements, providing invaluable data for health monitoring.

Each kit features a mmWave Sensor Module with:

• Light Level Sensing
• Customizable WS2812B RGB LED
• Support for Extended Grove Sensors/Actuators

Powered by the XIAO ESP32C6, these kits come with pre-flashed ESPHome firmware and support multiple wireless protocols, including Wi-Fi, Bluetooth Low Energy (BLE), Zigbee, and Thread. They are designed for easy no-code integration with Home Assistant via ESPHome, allowing users to customize detection zones and analytics. P.S. A 3D printing enclosure file is available for free download as a reference design to fit in your application.

Why Choose mmWave Sensors for Your Projects?

High Resolution and Accuracy: Essential for applications requiring precise detection and differentiation of human movements.

Non-contact and Non-invasive: Ideal for continuous monitoring without disturbance, crucial for healthcare and home environments.

Operational in Various Conditions: Functions effectively regardless of lighting conditions or physical barriers.

Privacy Preservation: Does not capture identifiable images or videos, ensuring privacy while monitoring.

Real-Time Processing: Supports immediate data processing for quick responses to detected emergencies.

Flexible Integration and Wide Coverage: Easily integrated into existing systems, enhancing capabilities without significant modifications.

Expanding Your Toolkit
