The Ångström distribution is in "competition" with Poky Linux[2] which is now part of the Yocto Project. Ångström is based on the OpenEmbedded project, specifically the OpenEmbedded-Core (OE-Core) layer. While both Ångström and Poky Linux are based on OE-Core, mostly utilize the same toolchain and are both officially "Yocto compatible", only Poky Linux is officially part of the Yocto Project.
Ångström primarily differs from Poky Linux in being a binary distribution (like e.g. the Debian, Fedora, OpenSuse or UbuntuLinux distributions), using opkg for package management. Hence an essential part of Ångström builds is a binary package feed, allowing to simply install software distributed as opkg packages, without having to compile them first (just as one might install a binary package with aptitude or dpkg).
Target platforms
