Table 7: Pin-out Information
: There are two different types of mPCIe modules; LE910Cx
mPCIe V1 and LE910Cx mPCIe V2. Two types of mPCIe modules have
different pinout on PCM signals but the rest of the pins are exactly the
same.
LE910Cx mPCIe V2 was developed to provide improved thermal
performance with the large solder resist opening area on the bottom
side of the module. For more details, refer to :

Pin-out for the Full Compatibility with PCI Express MiniCard
Specification.
Some pins of the LE910Cx mPCIe are different from the pin-out defined by the PCI
Express miniCard specification to support various functions of Telit.
But full compatibility with both PCI Express miniCard specification and Telit’s older xE910
mPCIe models was required. To meet this requirement, this model was developed.
