PCI Express
The conga-PA3 provides two PCIe interfaces – a half-size mini PCIe (mPCIe) slot on connector X8 and a half-size mini PCIe/mini SATA slot on
connector X9.
5.10.1
Mini PCIe (Half Size)
The conga-PA3 is equipped with a PCI Express Mini Card socket. The PCIe signals are routed directly from the SoC's PCIe lane 0 to connector
X8. The connector supports only mini PCIe devices.
The table below lists the default pinout of the PCI Express Mini Card.
