Thanks for clarifying your remarks. I’ll have to check the datasheet myself.

Did you find the value of idle current in your datasheet?

 

The value is not in the data sheet that you posted. If you can find another one for the Uno R3,it may mention it but I doubt it.

So, from where you have the value of idle current?

 

hi M.
May I ask why you need to know in such detail and how you are going to apply it to your project.?
Perhaps you should tell us what is the application/project you are working on, there maybe alternative ways of getting the required result.

I want to know the source of my information is in datasheet so I research on it or expermently.

I calculated power consumption of different digital system

 

hi M,
You may find this arduino power video helpful, it #1 of #3 video's

Did you not read my previous posts? I powered up four uno R3s and measured the current.
