    Hello,

    Is it possible to power only the intel curie processor (arduino) and not the Braswell processor by supplying 5V on the pin 9 ?


    Then if I ask the arduino to command something to provide 12 V to the pin Vin (pin 15), will all the board be working with pin 9 and 15 providing 5V et 12V at the same time?

    Thanks

    To OP
    View that 12V as the main and only power feeding source in UDOO x86 system design,
    It will in turn create 5V_always, 12V_always, 3.3V_always power rails.
    There are few system components expects these three "always" power rails be available all the time.

    It is not designed to be using Arduino 101 as the sole "Power Control" device, e.g., turning on/off the main 12V power supply at will to save the last available juice to the UDOO x86 board.

    If post #1 is your requirement, use an external/separate Arduino board (or any other low power embedded MCU board) with its own 5V (or 3.3V) power source, and use one of its GPIO pins to drive the 12V power_feed relay powering the UDOO.

    Note that Braswell x86 in sleep mode does not consume too much power in the first place.
