support expansion of modern motherboards that has no or limited numbers of MiniPCI Express
connectors. Adapter converts the x1 PCI Express motherboard slot into MiniPCI Express slot.

It includes one x1 PCI Express Host Card (Figure 2) and MiniPCI Express Adapter board (Figure
3). The x1 PCI Express Host Card has to be plugged into standard x1 PCI Express motherboard
connector. MiniPCI Express Adapter board connects to the PCI Express Host Card via 12” PCI
Express Flex cable. The expansion MiniPCI express add-in board has to be plugged into the
standard MiniPCI express connector on the MiniPCI Express Adapter board.
Because of the flexible nature of the connection (unlike traditional rigid risers), expansion
MiniPCI express add-in board can be positioned away from the PCI Express connector on the
motherboard inside a computer chassis.
MiniPCI Express Adapter board has two mounting holes allowing them to be securely fixed
inside a computer chassis.
The Adapter functions right out of the box, no additional software needs to be installed. The 32-
bit PCI Host Card has LEDs for displaying downstream PCI express Link status as well as
expansion MiniPCI express add-in board “PRESENT” status.
