Downloads

Zephyr project is provided as source code and build scripts for different target architectures and configurations, and not as a binary image. Updated versions of the Zephyr project are released approximately every three-months.

This downloads page is where you’ll find the latest tagged source code release along with its corresponding release notes found in the Zephyr Project GitHub repo.

  • All Zephyr project source code is maintained in a Git repository; you can either download source as a tar.gz file (see the bottom of the GitHub release notes pages listed below), or use Git clone and checkout commands, such as:

    git clone https://github.com/zephyrproject-rtos/zephyr
    cd zephyr
    git checkout tags/v1.8.0
  • The tools used to build an image are available as a Software Development Kit (SDK) in the Zephyr SDK Tools section below.

  • The project’s technical documentation is also tagged to correspond with a specific release and can be found at https://www.zephyrproject.org/doc/.
