As the most prominent SBC lineup, the Raspberry Pi family is compatible with a battalion of operating systems. Full-fledged desktop distros such as Kali Linux, Ubuntu, Debian, and the all-powerful Raspberry Pi OS provide a highly versatile experience. Alternatively, you could go for RetroPie, LibreElec, OpenMediaVault, or HomeAssistant if you want to devote your credit-card-sized board to a specific project.
