| + | Zephyr OS is a small, open-source real-time operating system (RTOS) designed for resource-constrained embedded and IoT devices, from tiny microcontrollers up to more capable edge hardware. It focuses on predictable, low-latency behavior with a preemptive kernel, strong configurability (you build only what you need), and broad hardware support through a clean device-driver model. Zephyr includes common embedded features like threads, synchronization primitives, timers, power management, networking stacks (e.g., TCP/IP, Bluetooth LE), and security options, all maintained under the Linux Foundation with an emphasis on portability, modularity, and production use. | ||
