It is possible to increase furthermore connectivity possibilities of CQ7-A42 carrier board using
the LPC signals coming out from Qseven
then carried out on a dual row, 14 pin, P2.54mm standard pin header, with
the pinout shown in the table on the left.
®
Please remember that Qseven specifications rel.2.0 share, on the same pins of the card
edge connector, the LPC signals with eight general Purpose I/Os; this means that whatever
interface is offered by the Qseven
connector.
In addition to LPC/GPIO signals, on this pin header is also available the Platform reset signal,
and the FAN_TACHOIN signal, which, according to the Qseven
also as a General Purpose Timer Input.
Please refer to the User Manual of the Qseven
It is possible to use SPI interface, coming out from Qseven
connector, for the connection of external SPI Devices (like EEPROM or Flash
devices, but any kind of SPI device can be connected).
For this purpose, it is available a dual row, 10 pin, P2.54mm standard pin header, with the
pinout shown in the table on the left.
On this pin header is also available the General Purpose 1-Wire signal. Please be aware, to
avoid malfunctioning, that this signal could have been used for implementation of HDMI_CEC
functionality (please check par. 3.3.5)
Please refer to the User Manual of the Qseven
