PCI-express slots
CQ7-A30 board offer a possibility of expansion through a standard PCI-e x16 card edge connector, type TE p/n 2-
1612163-4 or equivalent, with the pinout shown in the following table.
On this slot, are carried out the four PCI express lanes coming from Qseven
®
Card edge connector. Please be aware that
availability of all four PCI express lanes depends on the Qseven
®
module used.
Please check the User Manual of the Qseven
®
module used for details about the availability of these lanes.
It is also recommended to check that User Manual to see if these PCI-express lanes can be used in a grouped configuration, i.e. if they can be used in PCI-e x4
mode, in 2 x PCI-e x2, in 1 x PCI- e x2 + 2 x PCI-e x1, or if they must be strictly used in single lane configuration (i.e., four independent PCI-e x1 lanes).
