Internal USB/SATA Connectors Low Profile Mezzanine Module

Available as a mezzanine add-on expansion board to the CCM-BOOGIE and successor CPU carrier cards, the main purpose of the C41-CFAST is to provide a CFast™ host connector for attachment of a CFast™ storage card, as a rugged and fast mass storage media, which can be easy replaced. The C41-CFAST is designed to fit into the 4HP (20.32mm pitch) envelope of a CPCI CPU carrier board.

Further more, the C41-CFAST can be optionally equipped with an USB Silicon State Drive (SSD) module, or an USB type A host receptacle. In addition, two SATA connectors (latching headers) are optionally available on the C41-CFAST, for attachment of system internal drives by ordinary SATA cable harnesses.
