===={{Anchor|IIIAB}}Technical details of Mini PCI====
Mini PCI cards have a 2&nbsp;W maximum power consumption, which limits the functionality that can be implemented in this form factor. They also are required to support the CLKRUN# PCI signal used to start and stop the PCI clock for power management purposes.

There are three card [[computer form factor|form factors]]: Type I, Type II, and Type III cards. The card connector used for each type include: Type I and II use a 100-pin stacking connector, while Type III uses a 124-pin edge connector, i.e. the connector for Types I and II differs from that for Type III, where the connector is on the edge of a card, like with a [[SO-DIMM]]. The additional 24 pins provide the extra signals required to route [[input/output|I/O]] back through the system connector (audio, [[AC'97|AC-Link]], [[LAN]], phone-line interface). Type II cards have RJ11 and RJ45 mounted connectors. These cards must be located at the edge of the computer or docking station so that the RJ11 and RJ45 ports can be mounted for external access.
