I have a good few Odroid U3 SBCs I'm currently evaluating.
During this process I have been taking current measurements from
my bench supply whilst getting the U3 to perform various painful tasks such as 1080p
video playback and CPUBURN on 1,2,3 & all for all 4x 1.7GHZ cores.
Less demanding but more realistic I went through some web browsing, word processing
and Graphics "editing" with GIMP
Normal tasks 0.4-0.5A
CPU BURN 4cores 1.4A
1080p Movie playback 0.8-1.0A
