CoreExpress
CoreExpress modules are complete computer-on-modules (COM) that can be used like an integrated circuit. They integrate the core processing unit (CPU), memory, graphics, and BIOS, and common IO interfaces. The interfaces are legacy-free, only digital buses like PCI Express, SATA, Ethernet, USB, and HD audio (Intel High Definition Audio) are used. All signals are accessible on a high-density, high-speed, 220 pin connector. Although currently available implementations use Intel processors, the specification is open for other technologies, too.
CoreExpress modules are mounted on a custom carrier board, containing usually only the peripherals required for the specific application. In this way, small but highly specialized computer systems can be built.
The CoreExpress form factor was originally devised by LiPPERT Embedded Computers and standardized by SFF-SIG in 2010[1].
Size & Mechanics
The specification defines a board size of 58 mm x 65 mm, slightly less then a credit card.
The module can be embedded into a heat spreader, which takes care of removing the dissipated heat. Suitably sealed, the heat spreader also doubles as EMC protection.
Specification
The specification is hosted by the Small Form Factors Special Interest Group (SFF-SIG) and is available for download[2] on their website. The current revision 2.1 was released on February 23, 2010.
