Connector pinout for: PCI Express Card and PCI Express Mini Card
Like other PC buses, there are no glue logic devices just ASICs and chip sets in PCI Express; Similar to PCI. Refer to the LVDS page for additional information on the LVDS electrical interface. This page provides a comparison of Interface Switching levels for different types of electrical standards.

Mini PCI Express Bus Description
A Brief Description of the MiniCard interface. MiniCard is also called Mini PCI Express bus [PCI= Peripheral Component Interface]. The Minicard is a small form factor board used to implement the PCI Express interface on Notebook computers. The card size is 30mm wide by 50.95mm long by 5mm high. The Minicard uses a 52-pin card edge connector, the card pins are fingers at the edge of the card. MiniCard is used to implement both the 1x PCI Express Bus interface and a USB 2.0 interface.Mini PCI Express Bus Interface IC Manufacturers
Refer to the main PCI Express Bus for a list of manufacturers producing interface IC'sLike other PC buses, there are no glue logic devices just ASICs and chip sets in PCI Express; Similar to PCI. Refer to the LVDS page for additional information on the LVDS electrical interface. This page provides a comparison of Interface Switching levels for different types of electrical standards.

PCI Express Mini Card (also known as Mini PCI Express, Mini PCIe, and Mini PCI-E) is a replacement for the Mini PCI form factor based on PCI Express. It is developed by the PCI-SIG. The host device supports both PCI Express and USB 2.0 connectivity, and each card uses whichever the designer feels most appropriate to the task. Most laptop computers built after 2005 are based on PCI Express and can have several Mini Card slots.
