Info for all who seek to know the power draw of the Arduino Yun.
Every thing here is tested at 5V (USB) measured with a Fluke 115 meter:
Stock system booted, no connection, no sd: 200ma~270ma Seems to like to hover around 235~245ma but could peak to 300ma.
Stock system booted, with wired (cat5) networking: 277ma
Stock system booted, with wired (cat5) networking, max load: 315ma
I was a little shocked at how power hungry this device is. Lowest power draw seen was 170ma, in the first 1 second of booting. UBoot? So much for a low power Linux solution. :-(
