To add communications functionality, or other features not
already available, it is possible to use Half-/ Full-size mini-PCI
Express cards, using the dedicate connector, CN18, which is a
standard 52pin miniPCI Express connector, type LOTES AAA-
PCI-047-K01 or equivalent, H=9.0mm, with the pinout shown in
the table on the left.
CQ7-A30 carrier board allows inserting both Half-mini and Full-
mini PCI express cards. Support for both form factors is ensured
by the possibility, for the customer, of moving the mechanical latch in the position necessary
to support Half-miniPCI-e cards or Full-miniPCI-e cards.
On the slot are also available the signals for interfacing to miniSIM cards, so that it is possible
to use miniPCI Express modems.
As explained in the previous paragraph, PCI-e lane is available on CN18 when jumper JP1 is
not inserted, otherwise PCI-e lane #0 would be routed to PCI-e x16 slot CN14.
Signals carried to miniPCI-express slot are the following:
PCIE0_TX+/PCIE0_TX-: PCI Express lane #0, Transmitting Output Differential pair.
PCIE0_RX+/PCIE0_RX-: PCI Express lane #0, Receiving Input Differential pair.
mPCIE_CLK+ / mPCIE_CLK-: Reference Clock for miniPCI express slot, Differential Pair.
PCIE_WAKE#: Board's Wake Input, it must be externally driven by the miniPCI-e module
inserted in the slot when it requires waking up the system.
mPCIE_RST#: Reset Signal derived from those sent from Qseven
available on the board. It is a 3.3V active-low signal.
mPCIE_CLOCK_REQUEST# PCI Express Clock Request Input. This signal shall be driven
correctly by any module inserted in the miniPCI express slot, in order to ensure that the PCI-e
clock buffer available on the carrier board makes available the reference clock for the miniPCI-
e slot.
SMB_CLK: SM Bus control clock line for System Management, managed by the Qseven
module.
SMB_DATA: SM Bus control data line for System Management, managed by the Qseven
