power consumption

Hi, I can't seem to find what is the power consumption of the arduino board when power from an external source in mA. anybody can help ?



Depends on what are you doing in your code. It is best to measure it.

As said it varies depending on what your code is doing. The biggest variable is what you are controlling and powering from the I/O pins and if you are drawing power from the board to power external comonents. The basic board itself should draw at or less then 100ma would be the best quess I would make.


Another post on batteries says they have measured the current at 25mA when all unused inputs have the internal pull ups enabled. That is just the board not driving anything.
