Power consumption?

Development Boards Arduino
1

Hi all,

Could someone tell me what the power consumption would typically be for an Arduino with an ethernet shield?

(watts, or mA @ volts)

I just need a rough estimate of what to expect for a battery powered project. I’d measure the current draw, but I don’t have an Arduino yet.

Thanks.

Arduino by itself is on the order of 30-50mA.

The Ethernet shield is on the order of 200-300mA.
