CompactPCI® PlusIO CPU Card • Intel® Atom™ E6xx Series Processor

The PC2-LIMBO is a low power 4HP/3U CompactPCI® CPU board, equipped with an Intel® Atom™ E6xx series 1.6GHz processor, available on request for the industrial operating temperature range. The PC2-LIMBO front panel is provided with two Gigabit Ethernet jacks, two USB receptacles, and a DVI connector for attachment of a high resolution digital display.
The PC2-LIMBO is equipped with up to 2GB soldered RAM for rugged applications. An on-board CFast™ host connector is provided for attachment of a 3Gbps SATA SSD module. In addition, a microSD card holder can accommodate a low cost industrial microSDHC Flash card. Further more, several SATA based low mass storage expansion modules are available as an option. The PC2-LIMBO is equipped wit a set of local expansion interface connectors, which can be optionally used to attach a mezzanine side board. A variety of expansion cards is available, e.g. providing legacy I/O and additional PCI Express based I/O circuitry such as SATA and Gigabit Ethernet, or a secondary video output. Most mezzanine side cards can accommodate in addition a 2.5-inch drive.
Typically, the PC2-LIMBO and the related side card would come as a readily assembled 8HP unit. As an alternate, Flash based mezzanine storage modules are available that fit on the PC2-LIMBO while maintaining the 4HP profile. The C47-MSATA module e.g. accommodates two mSATA SSDs and can be operated in RAID mode. The C42-SATA module is provided with a 1.8-Inch Micro SATA SSD up to 800GB.
