14 PCI Express MiniCard
PCI Express MiniCard (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.
14.1 Connector
The interface is available through the standard PCI Express MiniCard connector J18 (52 pins).

Note: 1) To protect the external power lines of peripheral devices make sure that
- the wires have the right diameter to withstand the maximum available current.
- to enclosure of the peripheral device fulfills the fire-protecting conditions of IEC/EN 60950.
