PCI-e x4 Slots
CCOMe-C96 board offer a possibility of expansion through two standard PCI-e x4 card edge connectors, type WINWIN p/n WPES-
064AN41B22UWC or equivalent, with the pinout shown in the following table.
On first slot CN12, are carried out PCI-e lanes #0..#3 coming from COM Express connector (rows A-B).
On second slot CN14, are carried out PCI-e lanes #4..#7 coming from COM Express connector (rows A-B-C-D).
Please be aware that availability of all eight PCI express lanes depends on the COM Express module used.
Please check the User Manual of the COM Express module used for details about the availability of these lanes and all possible groupings that can be applied to
these lanes.
On CCOMe-C96 carrier board, the PCI-express compatibility is ensured with devices up to Gen3.
