The Intel-backed MinnowBoard.org project has shipped its first open source SBC for $199. The MinnowBoard runs a Yocto-compatible Angstrom Linux build on a 1GHz Intel Atom E640 with 1GB of DDR2 RAM, and provides SATA, gigabit Ethernet, USB, HDMI, and PCI Express interfaces, as well as stackable expansion boards called Lures.
