The LPC signals coming out from COM Express card edge connector are also
carried out on a dual row, 10 pin, P2.54mm standard pin header, with the pinout
shown in the table on the left.
The signals here available can be used for Debug Purpose, like to connect a POST code
display.
For further expandability of the system, on board there is an expansion connector, which
carries out the signals related to I2C bus, SM Bus and the two UARTs available on COM
Express card edge connector. These signals allow implementing, through external
expansion modules, further functionalities that are not already realised by the carrier board.
For this purpose, it is available a dual row, 14 pin, P2.54mm standard
pin header, with the pinout shown in the table on the left.
All the signals available on this connector come out directly from the COM Express
connector; please check the related table for a description of the signals.
