    Just for kicks I have a fan connected and powered by one of the Udoo usb ports. This morning I put the udoo in standby with the kodi remote. To my suprise the fan kept turning....

    Hi, it may be because usb allow to wake up the board, (like with a keyboard keypress), it need voltage in sleep mode.

    I thought so too. Anyone have any figures how much wattage is consumed by the Udoo x86 in standby mode? a Cursory glance at the datasheet gave no anwers.

    P=IE i.e. Power = Amps x Volts So, 53.7ma at 12 volts is .6444 watts and 59.8ma is .7176 watts.
