Can it be powered via the 40pin connectors 5V pin?

Is it possible to power the UP Board via the 40pin connectors 5V pin?

    Yes its possible
    but requires a good stabilized 5V power supply

    Thanks Nicola,
    I was planning to use TDK-Lambda CC6-2405SR-E right on the connector. It supplies only 6W though (5V, ~1A) so probably it will not be sufficient after all.

    Manual for up-board seems to indicate that it requres (5V, 4A) 20W power supply.

    Any data for actual power consumption ?

    Hi heel

    we have made some measurements with an embedded project that was reading data from two sensor via I2C and transmitting it every 10 seconds and the power consumption was like this:

    (up boardwith 1 Gb without display with lan disabled and a GSM module on USB):
    Mean Current (5V power supply) 350mA
    Mean power (5V power supply) 4.12w
    
    Peak Current (5V power supply) 457mA
    peak power (5V power supply) 5.5W
    

    Of course if you plan to use a Desktop environment/Video or CPU hungry task, or to connect USB devices you need the suggested power supply.

    my application is also embedded control.
    thanks nicola for the comprehensive answer - perfectly the answer I was looking for. br henning

    Ni Nicola,

    How do you get:

    " Mean Current (5V power supply) 350mA
    Mean power (5V power supply) 4.12w " ?

    If your mean current draw is 350mA @ 5V shouldn't the mean power consumption be 0.35A x 5V = 1.75W?
