4.2.2 PCI Express Slot X1
Table 4-5 illustrates the pinout definition for the standard x1, x4, x8 and x16 PCI
Express connectors. The dashed lines in the diagram depict where each different
connector type ends. An example of an x1 PCIe slot is shown in Figure 4-5 below.

4.2.3 Express Card Connector
Hot-swappable Express Cards come in a small form factor and are designed primarily
for mobile computing. The card’s electrical interface is thru USB 2.0 or a single x1
PCIe link. Express Cards are the successor to Card Bus Cards (which are PCI-based).
Card Bus cards, in turn, are the successors to PCMCIA cards. All three formats are
defined by the PCMCIA Consortium.
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
In addition to the signals of a PCI Express x1 link and a USB 2.0 link, the ExpressCard
interface requires the following control signals provided by the COM Express module.
The corresponding signals can be found on the module connector rows A and B.
