Supported Zephyr SDK targets wireless IoT

The Simplicity SDK for Zephyr from Silicon Labs is a downstream, fully supported distribution of the Zephyr RTOS optimized for Silicon Labs wireless platforms. The SDK combines Zephyr’s modular RTOS architecture with validated wireless stacks, drivers, and consistent behavior across Series 2 devices, providing a predictable and production-ready software path for long-lifecycle IoT products. Initial support includes EFR32xG22, xG24, xG27, and xG29 devices, enabling developers to adopt Zephyr while maintaining access to vendor-backed testing, QA, and lifecycle support.
