Matter is a revolutionary technology that allows for consistent operation between smart home devices and IoT platforms without an Internet connection, even from different providers. This means that Matter can communicate between major IoT ecosystems to create a single wireless protocol that is easy, reliable, and secure to use.
The SparkFun Thing Plus Matter - MGM240P comes with Qwiic and LiPo battery connectors, and multiple GPIO pins capable of complete multiplexing through software. It also features the MCP73831 single-cell LiPo charger and the MAX17048 fuel gauge to charge and monitor a connected battery. An added bonus is the µSD card slot for any external memory needs.
The MGM240P wireless module is equipped with the EFR32MG24 Wireless SoC and a 32-bit ARM Cortext-M33 core processor running at 39 MHz with 1536 kb Flash memory and 256 kb RAM. It works with common 802.15.4 wireless protocols (Matter®, Zigbee®, and OpenThread®), as well as Bluetooth® Low Energy 5.3, and supports Silicon Labs' Secure Vault™ for Thread applications.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields, and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

Features of the SparkFun Thing Plus Matter - MGM240P include the MGM240P Wireless Module built around the EFR32MG24 Wireless SoC. It has a 32-bit ARM-M33 Core Processor (@39MHz), 1536kB Flash Memory, 256kB RAM, and supports Multiple 802.15.4 Wireless Protocols (Zigbee and OpenThread). It also supports Bluetooth Low Energy 5.3, is Matter-ready, and has Secure Vault Support with a built-in Antenna.
The Thing Plus Form-Factor (Feather-compatible) has dimensions of 5.84cm x 2.29cm, with two mounting holes that are 4-40 screw compatible. It has twenty-one GPIO PTH Breakouts, all pins have complete multiplexing capability through software, SPI, I2C and UART interfaces mapped by default to labeled pins, thirteen GPIO (Six labeled as Analog, seven labeled for GPIO), all function as either GPIO or Analog, and a built-in-Digital to Analog Converter (DAC).
Other features include a USB-C Connector, 2-Pin JST LiPo Battery Connector for a LiPo Battery (not included), 4-Pin JST Qwiic Connector, MC73831 Single-Cell LiPo Charger with a configurable charge rate (500mA Default, 100mA Alternate), MAX17048 Single-Cell LiPo Fuel Gauge, µSD Card Slot, and Low Power Consumption (15µA when MGM240P is in Low Power Mode).
LEDs on the board include PWR - Red Power LED, CHG - Yellow battery charging status LED, and STAT - Blue status LED. There is also a physical push-button Reset Button, and the reset signal can be tied to A0 to enable use as a peripheral device.
