SparkFun Thing Plus Matter – MGM240P

The SparkFun Thing Plus Matter is the first easily accessible board of its kind that combines Matter and SparkFun’s Qwiic ecosystem for agile development and prototyping of Matter-based IoT devices. The MGM240P wireless module from Silicon Labs® provides secure connectivity for both 802.15.4 with Mesh communication (Thread) and Bluetooth® Low Energy 5.3 protocols. The module comes ready for integration into Silicon Labs’ Matter IoT protocol for home automation. SparkFun’s Thing Plus development boards are Feather-compatible and include a Qwiic connector for easy integration into our Qwiic Connect System for solderless I2C circuits.

What is Matter? Simply put, Matter allows for consistent operation between smart home devices and IoT platforms without an Internet connection, even from different providers. In doing so, Matter is able to communicate between major IoT ecosystems in order to create a single wireless protocol that is easy, reliable, and secure to use.

The Thing Plus Matter – MGM240P includes Qwiic and LiPo battery connectors, and multiple GPIO pins capable of complete multiplexing through software. The board also features the MCP73831 single-cell LiPo charger as well as the MAX17048 fuel gauge to charge and monitor a connected battery. Lastly, we’ve included a µSD card slot for any external memory needs.

The MGM240P wireless module is built around the EFR32MG24 Wireless SoC with a 32-bit ARM Cortext-M33 core processor running at 39 MHz with 1536 kb Flash memory and 256 kb RAM. The MGM240P works with common 802.15.4 wireless protocols (Matter®, Zigbee®, and OpenThread®) as well as Bluetooth® Low Energy 5.3. The MGM240P supports Silicon Labs’ Secure Vault™ for Thread applications.
