Overview
The SparkFun Thing Plus Matter - MGM240P brings Matter, Thread, Zigbee, and Bluetooth 5.3 connectivity to the popular Thing Plus (Feather-compatible) form factor. At its core is the Silicon Labs MGM240P multiprotocol wireless module — an ARM Cortex-M33 running at 78MHz with 1536KB flash, 256KB RAM, and a powerful +20dBm radio for extended wireless range.
Designed for rapid prototyping, the board includes a Qwiic connector for plug-and-play I2C sensor integration, a microSD card slot for local data storage, and a LiPo battery charging circuit with MAX17048 fuel gauge for battery-powered deployments. The MCP73831 charger supports both 100mA and 500mA charging rates.
With 23 GPIO pins broken out to standard 0.1" headers in the Thing Plus layout, it is Feather-compatible and works with the vast SparkFun and Adafruit ecosystems. A Mini Simplicity connector allows connection to Silicon Labs' Simplicity Studio IDE and external debuggers for professional development workflows.
The MGM240P is certified for Matter and supports all major 802.15.4 mesh protocols, making this board ideal for building Thread end devices, Matter accessories, and Zigbee nodes that integrate with Apple Home, Google Home, Amazon Alexa, and SmartThings.
