I'm building a project which needs to be able to run for as long as possible on a battery. I am running my Arduino with an Ethernet Shield.
I'm finding that in total the boards are drawing around 180mA - I was hoping to keep this below 100mA. I tested the Arduino board on it's own and it appears to only draw around 30mA.
So, it looks as though the Ethernet Shield is responsible for 150mA of current draw. Has anyone else found this? And if so, has anyone found a way to reduce the power consumption of the module? I was wondering if there was a way to modify the ethernet library to eliminate the indicator LEDs or something similar - every mA counts :D
Thanks to all in advance.
