Zephyr
Zephyr is a scalable, open-source real-time operating system (RTOS) designed for resource-constrained embedded systems, such as microcontrollers and IoT devices. It provides a modular architecture with support for multiple hardware architectures, memory protection, and connectivity protocols like Bluetooth, Wi-Fi, and Thread. Developed under the Linux Foundation, it emphasizes security, power efficiency, and portability for diverse embedded applications.
Developers should learn Zephyr when building embedded systems or IoT devices that require a lightweight, secure, and real-time operating system, such as wearables, industrial sensors, or smart home gadgets. It is particularly useful for projects needing cross-platform compatibility, low power consumption, and support for modern connectivity standards, as it offers a robust ecosystem with extensive driver support and community contributions.
