EXPRESS

The smartCoreExpress supports small footprints and especially mobile applications. It is powered by the
modern Intel Atom CPU technology.

To select the correct module, this chapter compares the different PCIe-based module concepts. All concepts
allow minimum (required) and maximum (optional) features.

The following table summarizes the features of all PCIe COMs.

Examples:

2 / 6

= 2 required, 6 optional from each module

1 / 1 (PCIe) = 1 required, no more optional, 1x PCI lane needed.

Depending on the concept, reduces the number of free PCIe lanes.
