'''Mini PCI''' was added to PCI version 2.2 for use in [[laptop]]s and some routers;{{cn|date=April 2024}} it uses a 32-bit, 33&nbsp;MHz bus with powered connections (3.3&nbsp;V only; 5&nbsp;V is limited to 100&nbsp;mA) and support for [[bus mastering]] and [[direct memory access|DMA]].  The standard size for Mini PCI cards is approximately a quarter of their full-sized counterparts. There is no access to the card from outside the case, unlike desktop PCI cards with brackets carrying connectors.  This limits the kinds of functions a Mini PCI card can perform.

Many Mini PCI devices were developed such as [[Wi-Fi]], [[Fast Ethernet]], [[Bluetooth]], [[modem]]s (often [[Softmodem|Winmodems]]), [[sound card]]s, [[cryptographic accelerator]]s, [[SCSI]], [[Integrated Drive Electronics|IDE]]–[[AT Attachment|ATA]], [[SATA]] controllers and combination cards. Mini PCI cards can be used with regular PCI-equipped hardware, using Mini PCI-to-PCI ''converters''. Mini PCI has been superseded by the much narrower [[PCI Express Mini Card]]

===={{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.
