Zephyr Project

aid: zephyr
name: Zephyr Project
description: >-
  The Zephyr Project is a Linux Foundation project that delivers a small,
  scalable, secure, and open-source real-time operating system (RTOS) for
  resource-constrained embedded devices. Zephyr supports 1000+ boards across
  ARM Cortex, RISC-V, ARC, x86, Xtensa, and other architectures, ships with a
  C kernel, device drivers, networking stacks (BLE, Wi-Fi, Thread, Matter),
  security subsystems, and is supported by a meta-tool (west), an SDK
  (sdk-ng), and a broad ecosystem of training partners and commercial
  silicon and module vendors.

    description: >-
      The Zephyr kernel C API exposes scheduling, threading, synchronization,
      memory management, and timer services for real-time embedded
      applications. It is the foundation that device drivers and application
      code build on.

    description: >-
      The Zephyr device driver subsystem exposes a uniform device model
      across GPIO, I2C, SPI, UART, ADC, sensors, displays, networking, USB,
      Bluetooth, and many other peripheral classes, configured through
      Devicetree and Kconfig.
