    Onboard DC-DC PSU

    I was looking at a Dual core Atom + Ion combo as a carputer, and I noticed it came with a 40w onboard DC-DC PSU. Does this mean I can't set it up for a car?

    It requires regulated 12v and your vehicle's electrical system doesn't provide regulated 12v.
    Can you use the board? Sure, with a regulator.
    Have you looked in the FAQ yet?
    How about the Wiki?

    slight correction-- there is no link to the product your talking about, so i can't be sure that it has a on-board 12 volt dc-dc. many atom boards have a 19v power adapter, which would have different in-car power supply requirements.

    saying it uses dc-dc power is like asking why your Ford won't start-- there are many variations within the category, and all of them can have different solutions.

    http://www.newegg.com/Product/Produc...82E16813500027 is the product I am looking at.

    doesn't say the input voltage on the details page.
    you need atleast 9-16. or you will probably burn the dc-dc converter when you start te car
    (car running is13.8 volts or higher)
    Car system in the making:
    dualcore atom
    M2 atx psu
    screen??

    The board requires regulated 19v.
    Your vehicle can't output that voltage, so look at a Carnetix.
