During May 2026, this developer contributed to the Zephyr4Microchip/zephyr repository by adding support for the Arduino Nano RP2040 Connect board, expanding Zephyr’s compatibility with Arduino hardware for IoT applications. The work involved implementing board-level configurations and integration patterns, drawing on the Raspberry Pi Pico reference to ensure consistency and reliability. Using C programming and device tree configuration, the developer enabled robust hardware integration and streamlined IoT-ready deployments. This addition broadens Zephyr’s hardware support, allowing faster time-to-market for projects targeting the Nano RP2040 Connect, and demonstrates a focused approach to embedded systems and IoT development within the Zephyr ecosystem.
