SparkFun Thing Plus Matter MGM240P – Robust IoT Applications with Zigbee and More


The SparkFun Thing Plus Matter board is the first Matter-compliant, an easy-to-use board that integrates with SparkFun’s Qwiic ecosystem and a host of communication protocols like Zigbee for agile development and prototyping of Matter-based IoT devices at just $24.95 plus shipping.

The Matter is a new standard for smart home devices that offers advantages such as interoperability, increased compatibility with voice assistants and platforms, enhanced security, simplified setup, and future-proofing. Matter devices can communicate with each other regardless of the manufacturer, protocol, or operating system, which simplifies smart home ecosystem integration.

The board contains MGM240P wireless module, which is built around EFR32MG24 Wireless SoC which works with common 802.15.4 wireless protocols like Zigbee, Matter, OpenThread, and Bluetooth Low Energy 5.3. This module can be directly integrated into Silicon Lab’s Matter IoT protocol for home automation. Apart from this, the MGM240P has built-in support for Silicon Lab’s Secure Vault for applications involving Thread protocol like smart home.


Apart from the ease of connectivity and support for a wide range of communication protocols, it also includes a µSD card slot for any external memory needs and MCP73831 single-cell LiPo charger as well as MAX17048 fuel gauge to charge and monitor a connected battery. Also, it contains Qwiic and LiPo battery connectors, as well as multiple GPIO pins capable of complete multiplexing through software. Software Multiplexing is a highly important feature that is significant for some IoT use cases where multiple devices need to share the same physical resource, such as a communication channel or a physical I/O pin.
