Raspberry Pi Power Usage - Testing?

wallarug
wallarug over 12 years ago

Has anyone done any power usage testing with the raspberry pi and/or its official camera board?


I am wondering exactly how much the camera uses when it is in use and when it is idle for a project that I am working on.  No-one on the other forum seems to have completed power usage testing with the camera.


There is however some testing done with just the Raspberry Pi and those results are very interesting. 

http://www.raspberrypi.org/phpBB3/viewtopic.php?f=29&t=32955

 

Results:


For comparison the model B 256M (default clocks):

Idle (console): 0.372A 1.89W

Idle (lightdm running): 0.375A 1.91W

Running scp from SD card: 0.413A 2.09W


Model A (default clocks)

Idle (console): 0.113A 0.587W

cat /dev/urandom | gzip: 0.153A 0.795W


Model A (ARM=350MHz overvolt=0)

Idle (console): 0.111A 0.576W

cat /dev/urandom | gzip: 0.133A 0.691W


Model A (ARM=350MHz overvolt=-8)

Idle (console): 0.106A 0.554W

cat /dev/urandom | gzip: 0.125A 0.652W

 

 

 

Is there anyone who can test the camera and post their results... I am very interested.

    Has anyone made any progress on this area?  I would really like if someone could test a model A and the camera recording a video, then taking a still.  I want to know if @JamesH 's estimates of 250mA - 270mA are correct for a battery powered project.

    I don't have a model A, but I'll get you some relative numbers for a 256M model B with the camera operating that should give you some idea of what the additional power requirements are when using the camera.
