Arduino ABX00137 Nano Matter Board

Arduino ABX00137 Nano Matter Board is a compact, feature-rich development board designed for Matter and Thread-based Internet of Things (IoT) applications. Built around the Silicon Labs MGM240SD22VNA microcontroller, the board features a 32-bit Arm^® Cortex^®-M33 CPU with 1536kB Flash and 256kB RAM, making it well-suited for low-power wireless communication. The board supports BLUETOOTH^® Low Energy (BLE), Zigbee, and Thread protocols, and is Matter-compliant, enabling seamless integration with smart home ecosystems. The Arduino ABX00137 includes a USB Type-C^® connector for power and programming, built-in Secure Vault^® security for safeguarded communication, and a rich set of I/O options including digital, analog, PWM, and I²C interfaces. The small form factor and Arduino IDE compatibility make it an excellent choice for developers building secure, connected devices in constrained environments.

The Arduino Nano Matter Board is offered in two variants. Part # ABX00112 features castellated/through-hole pins for SMD mounting, while part # ABX00137 features pre-installed headers for easy prototyping.
