4.3 PCI Express x1 Slots

One PCIe x1 slot is assigned to each of the 6 PCIe lanes of the COM Express module.

Note: The order of the connectors has changed on the new layout. Now X6 is near PEG

slot.

Note : The number of PCIe lanes available will depend on the COM Express module

used – not all modules can support 6 PCIe lanes.
