Maintainers and community have deep understanding how HW work. We are seniors with 30+ years of experience in Linux + embedded Linux.

Open

Armbian provides open source build framework to build a distribution of optimised Linux hardware interface for armhf, aarch64 and x86.

We provide a selection of images that fits hardware best. If you need different image – use build framework and make whatever you need. Build framework relies on Debian and Ubuntu packages – you can build any combination – stable, old stable or rolling release.

Minimal images comes without armbian-config, armbian-zsh, build-essentials, Python, DKMS, … If you are interested in detailed comparison, CLI images also have those packages:

• Debian Bullseye
• Ubuntu Jammy

Make sure you have a good & reliable boot media (SD card / USB key) and a proper power supply. Archives can be flashed with Etcher (all OS) directly.

Insert the SD card into the slot, connect a cable to your network if possible or a display and power your board. (First) boot (with DHCP) takes a bit longer.
