miniPCIe
Mini PCI Express (mPCIe) is a hardware expansion standard defined by PCI-SIG for a small form-factor card and corresponding edge connector used in laptops, tablets, and embedded systems. It evolved from the original Mini PCI design and provides a modular way to add PCI Express devices without large motherboard changes. The standard specifies two commonly used card sizes—half-size and full-size—and a 52-pin edge connector that carries PCI Express signals, usually a PCIe x1 link, along with USB 2.0 signals and other management lines.
A mini PCIe card typically uses a PCI Express interface (often x1) to communicate with the host,
Common uses for mPCIe cards include wireless network adapters (Wi‑Fi and Bluetooth), cellular modems, GPS, and,
In modern devices, mini PCIe has largely been superseded by the M.2 (NGFF) standard, which offers higher
