PCI Express Mini Card
The conga‑CEVAL is equipped with a PCI Express Mini Card socket (M40). PCI Express Mini Card is a unique small size form factor optimized
for mobile computing platforms equipped with communication applications such as Wireless LAN. The small footprint connector can be
implemented on carrier board designs providing the ability to insert different removable PCI Express Mini Cards. Using this approach gives the
flexibility to mount an upgradable, standardized PCI Express Mini Card device to the carrier board without additional redesign cost. The PCI
Express Mini Card uses USB port 7 and PCI Express lane 5 by default.
The following table lists the default pinout of the PCI Express Mini Card.
