Connectors on ET900
J2, J3: COM Express Type 2 Connectors
The Type 2 connectors come in two 220-pin 0.5mm pitch receptacles. They include PCI, IDE, GBE and up to 22 general-purpose PCIE lanes (PCIE 0-5 and PCIE 16-31). For most Type 2 implementations, it is expected that PCIE lanes 16-31 are used for graphics. Hence they are designated PEG lanes 0-15 in the following table. Modules implementing Pin out Type 2, such as the ET900, uses the pin-out shown.
