    Hello to everybody,
    I am wondering if with any of the UDOO boards is it possible to run Arduino code in the background when the UDOO is plug to the mainline but switched off (or at least in sleep mode).

    I am asking this because I would like to keep logging data from sensors (environmental sensors) attached to the GPIO without keeping the main board on. So it's essential that the Arduino can write data to memory.

    Best regards,
    Giacomo

    All Udoo boards except the Neo can put the PC part into sleep mode and let the Arduino hardware continue running. You have to attach an extra SD card if you want to store extra data.

    The Udoo Neo is so small and power consumption is pretty low that perhaps it could also fulfill your needs without sleep mode.

    For the Quad and X86 your Arduino sketch has to be prepared for a Arduino sketch reset as the Arduino gets reset as the PC part is booting op. For the Bolt I do not know.

    Thanks a lot for the answer!! I really appreciated it! I was thinking to create a data logger for humidity and temperature, but in this case, it seems more suitable to go with a standard computer and an external datalogger with the RH sensors attached.

    It's a pity that there is no way to have a share data space between Arduino and UDOO. It shouldn't be hard to add a little SD card reader where both can write and read from.
