3.2.3 PCIe Mini Card
The PCI Express Mini Card add-in card is a small size form factor optimized for mobile
computing platforms equipped with communication applications such as Wireless LAN. A
small footprint connector can be implemented on the carrier board providing the ability to
install different PCI Express Mini cards. In addition to a PCI Express x1 link and a USB 2.0
link, the PCI Express Mini card interface utilizes the following control and reset signals,
which are provided by the COM Express module connector rows A and B.
