PCI Express host  board connects to the motherboard x1/x4/x8/x16 PCI Express connector (upstream). Flat PCI Express cables (10 inches) are used for connection between host board and adapter boards and provide flexible connection between MiniPCI expansion boards and the motherboard.

The power for MiniPCI add-in board (5V and 3.3V) is supplied via 124-pin MiniPCI connector. The MiniPCI adapter board has standard 4-pin “Floppy drive” power connector for getting power (5V) from standard ATX power supply or any external 5V power source.

MiniPCI adapter board has 3 mounting holes for its mechanical fixation inside the computer chassis (embedded computer).
