It is possible to increase furthermore connectivity possibilities of CQ7-D59 carrier board using
the LPC signals coming out from Qseven
a dual row, 14 pin, P2.54mm standard pin header, with the pinout shown in the table on the
Signal

Please refer to the User Manual of the Qseven
It is possible to use SPI interface, coming out from Qseven
connection of external SPI Devices (like EEPROM or Flash devices, but any kind of SPI device
can be connected).
