The Zephyr Project is hosted by the Linux Foundation. The purpose of the Zephyr Project is to develop a small and scalable real-time operating system (RTOS).

The Zephyr RTOS is open source and modular. This RTOS allows developers to build anything from a small connected sensor to a small wireless gateway based on an Arm processor.
