wikiPCI Express Mini Card (Mini PCIe)
The PCI Express Mini Card specification (Mini PCIe) was published by PCI-SIG as successor of Mini PCI in 2003. The specification defines the implementation of PCI Express cards in a small form factor. The form factor is used, for example, for Mini PCIe WLAN and Bluetooth modules.
PCI Express Mini Card (Mini PCIe) features
Features of PCI Express Mini Card:[1]
- Card dimension: 30mm x 51mm x 5mm
- Signals:
- PCI Express 1.0 x1
- USB 2.0 (USB 3.0 is additionally supported since 2014, but USB 3.0 cannot be used parallely (compared to USB 2.0) as USB 3.0 uses the same PINs like PCIe[2]
Successor of the PCI Express Mini Card and mSATA specification is the PCI Express M.2 specification. M.2 supports PCIe 3.0 up to x4 lanes, SATA 3.x and USB 3.0 as well as smaller card dimensions.
