ExpressCard
The conga‑CEVAL is equipped with an ExpressCard slot (connector X16). ExpressCard is a small, modular add‑in card designed to replace
common PCMCIA and PC Cards. It takes advantage of the scalable, high-bandwidth serial PCI Express and USB 2.0 interfaces to provide
much higher data rates. COM Express™ modules offer support for up to two ExpressCard slots. More information about the ExpressCard
Standard can be found at http://www.expresscard.org.
The following table lists the default pinout of the ExpressCard slot. It utilizes USB port 6 and PCI Express lane 2 by default.
