Silicon Labs and Arduino Team Up to Democratize Matter

February 12, 2024 by Jake Hertz

Matter-over-Thread applications are now more accessible to Arduino's developer community of 33 million.

Matter aims to unify the fragmented IoT ecosystem, offering a universal language through which an array of devices can communicate seamlessly, regardless of the manufacturer. The promise of this protocol is to simplify IoT development, making smart technology more interoperable and accessible to everyone.


Matter-over-Thread applications

Designers can now develop Matter-over-Thread applications using the Arduino IDE on the EFR32MG24 MCU. 

Recently, Silicon Labs and Arduino announced a new phase in their partnership aimed at democratizing the development of Matter-enabled IoT devices. The two companies will do this by integrating the Matter protocol into the Arduino ecosystem.


Silicon Labs and Arduino Show Support for Matter

Silicon Labs and Arduino unveiled Phase 1 of the collaboration at CES 2024. This phase introduced a Matter-tailored Arduino library and an Arduino core for Silicon Labs microcontrollers, bringing these solutions into the Arduino integrated development environment (IDE).

The partnership's second phase is geared toward the launch of a new development board within the Arduino Nano family. This board, based on the Silicon Labs MGM240 module, is designed to further streamline IoT development.

This partnership aims to significantly lower the barrier to entry for developing Matter-over-Thread devices by integrating Matter with Arduino's ecosystem. A wider range of both hobbyist and professional developers can now easily create secure, energy-efficient, and powerful IoT devices using the Matter software libraries for Arduino alongside hardware like the xG24 Explorer Kit and the SparkFun Thing Plus Matter MGM240P development board.


MGM240 Module: The Heart of Arduino's New Board

The new Arduino board will be based around the Silicon Labs MGM240 module, which relies heavily on Silicon Labs' EFR32MG24 SoC. The SoC provides the MGM240 module with a 32-bit, 39-MHz Arm Cortex-M33 processor, including DSP extensions and a dedicated floating point unit (FPU), along with 1,526 kB of Flash memory and 256 kB of RAM.

The device is built around a high-performance 2.4-GHz radio subsystem. The radio subsystem operates with a built-in antenna multiprotocol radio, supporting 802.15.4 and BLE 5.3. With a sensitivity of -106.0 dBm at 250 kbps using O-QPSK modulation, the module can detect and process very weak signals—a crucial feature for maintaining connectivity in environments with high levels of interference or over extended ranges. Furthermore, the module can deliver up to 19.9 dBm output power, ensuring that signals can be transmitted over long distances or through obstacles. 

Energy efficiency is also a critical aspect of the MGM240 module, with features designed to minimize power consumption. The module boasts an EM2 DeepSleep current of just 1.3 μA and an active mode (EM0) current consumption of 33.4 μA/MHz, making it suitable for battery-powered applications where longevity is paramount​.


More Accessible IoT Development to Come

Silicon Labs and Arduino hope their collaborative efforts will catalyze a wave of innovation across various sectors, including smart homes, industrial IoT, and educational projects. The convergence of Arduino's user-friendly platform with Silicon Labs' hardware, all underpinned by the universality of the Matter protocol, may signify a major leap forward for the embedded engineering community.
