Zephyr RTOS

Zephyr is an open-source, real-time operating system (RTOS) hosted by the Linux Foundation, specifically engineered for resource-constrained and embedded systems like IoT devices, wearables, and sensor networks. It features a highly scalable, small-footprint kernel that is architecture-agnostic, supporting a broad range of microcontrollers and processors. With a strong emphasis on security, connectivity, and modularity, Zephyr enables developers to build sophisticated, connected products while maintaining the deterministic performance required for time-sensitive tasks.
