2.5-Inch SATA SSD/HDD Mezzanine Storage Module

Available as a mezzanine add-on expansion board to several EKF CPU carrier cards, the main purpose of the C44-SATA is to accommodate a 2.5-inch SATA drive, either SSD (Solid State Drive) or HDD (Hard Disk Drive). In addition, the C44-SATA provides eSATA and USB connectors for front panel I/O. Since only a few active components are required on the C44-SATA PCB, it is a reasonable low cost system expansion module.

Two eSATA connectors are available via the C44-SATA front panel, for attachment of external drives by eSATA cable harnesses. In addition, three USB 2.0 receptacles are situated in the front panel, for general use.

The C44-SATA mounts on top of the CPU carrier board, with a 4HP pitch off-stand, resulting in a 8HP front panel for the entire dual-board assembly.
