Dual M.2 PCIe® SSD Sockets • Versatile Front I/O

Available as a mezzanine add-on expansion board (aka side card) e.g. to the PC7-FESTIVAL CompactPCI® PlusIO CPU, the PCZ-NVM is equipped with two M.2 SSD module sockets, as a rugged mass storage solution. In addition, frequently required I/O functions (RS-232, USB 3.0, DisplayPort) are provided via front panel connectors.

Both M.2 sockets are suitable for PCIe® based SSD modules (M-key) up to the 2280 format. The upper connector establishes a PCIe® Gen3 link x4 or will be automatically switched to SATA mode for a legacy SSD. The lower connector M.2 socket supports a PCIe® Gen3 link x2.
