Re: The Future of the Pi A series

You're not trying very hard if you can't get the Pi2 above 200mA... Well, the figures are what they are: a simple comparison under similar conditions. I guess you need to compare the B+ with the 2B doing the same job. i.e. does the 2B draw more current than the B+ when running your favorite heavy w...
