Hello,
are there data about routerboards power consumption?
In the data sheet are listed simply voltage and current needs, what I would like to know is power consumption related to the wireless card(s) installed.

Wireless card consumption depends on the wireless card.
RouterBOARD 411AR power consumption from User Guide,

Power consumption 3-4W without extension cards, maximum – 12W
3-4W without the card and 8-9W left for the extension cards.
