CoreExpress
CoreExpress modules are complete Computer-on-Module, (COM) highly integrated, small and compact PCs that can be used in an embedded computer board design, much like an integrated circuit component. COMs integrate (CPU), memory, graphics, and BIOS, and common IO interfaces. The interfaces are legacy-free, using only digital buses such as PCI Express, SATA, Ethernet, USB, and HD audio (Intel High Definition Audio). 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 different CPU CoM solutions.
CoreExpress modules are mounted on a custom carrier board, containing 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 developed 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 than 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.
