3.3.17 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.
