Feature internal pin header 

For further expandability of the system, on board there is an expansion connector, which carries out the signals related to Watch Dog, I2C bus, SM Bus, thermal 
and power management. 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,  28  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 Qseven

®

 connector; 

please check the related table for a description of the signals.
