The MinnowBoard community website reports that Intel is now shipping its MinnowBoard bare-bones PC. It's a bit heftier in price than the Raspberry Pi, costing $199 USD, and can be purchased at Digi-Key, Farnell, Mouser Electronics and Newark. Additional outlets will be added soon.
Intel's MinnowBoard sports an Atom E640 SoC clocked at 1 GHz, integrated GMA 600 graphics, 1 GB of DDR2 RAM, and 4 MB of SPI flash for system firmware memory. The I/O portion contains one microSD card slot, one SATA 2 (3 Gb/s) port, two USB host ports, one microUSB-B port, a serial (UART 0) port for debug serial to USB conversion, a Gigabit Ethernet port, and HDMI output.
The board's "experimenter" features include eight buffered GPIO pins, two experimenter GPIO controlled LEDs, four experimenter GPIO switches, and a system firmware flash programming header (Dedi-Prog compatible). The board boots using open-source UEFI firmware with Fast Boot capability, and the shipped OS of choice is the Angström Linux distribution, which is compatible with Yocto Project.
The board's actual dimensions are 4.2 x 4.2 inches, and can be expanded using daughter cards called "Lures." These cards can be custom developed to "expose features and interfaces as required for developer applications." Lure specifications for the MinnowBoard can be found here, and includes an Automotive Lure and a MiniPCIe/mSATA Lure.
A joint project with CircuitCo Electronics, the MinnowBoard is Intel's first "open source," bare-bones PC aimed at software developers. It's also supposedly the first of its kind to ship with an x86 chip on-board. Price wise, it's closer to some of Zotac's solutions than Raspberry Pi or Arduino, but that could change if units aren't flying off the shelves of the retailers mentioned above.
"Where the MinnowBoard really shines is in its I/O performance," said Scott Garman, embedded Linux engineer at Intel’s Open Source Technology Center. "Powered by PCI Express, you can make full use of SATA disk support and gigabit Ethernet for high throughput applications such as file servers or network appliances."
Intel has several guides up on the MinnowBoard website including an introduction that takes users from unboxing to booting up the OS, toggling one of the two LEDs from the Linux command line and GPIO programming. These are currently in PDF format and will supposedly see HTML-based versions in the near future. The board's schematics and design are also published under a Creative Commons license.
