    Announcing M2-ATX vehicle PSU:

    Based on a modified design of the M1-ATX, but with a stronger 12V rail, here are some preliminary specifications. Also, please see picture below.
    NOTE: Microcontroller softtware remains the same.

    MAX
    5V 10A
    5VSB 1.5A
    3.3V 10A
    12V 8A
    -12V 0.1A

    On the 12V rail, I was able to push it to 10A, but things got very hot....
    Also, keep in mind that at full load you would need a fan to blow over the PCB, some derating will need to occur.

    Please do not take these specs as final, some more testing / derating needs to occur.

    Should you need a notification when the M2-ATX icomes out from production, please send an email to [email protected]

    Enjoy,
    -A

    Probably from the MP3car.com on-line store. You must be patient, this PSU is still in the quoting process, it will probably take ~2 months for the first lot to come out, should everything go as planned.

    Just a thought. If you can make ATX connector on a board 180 deg rotated so the snap in version can be something easy to have. And 10x16 capacitors is a must.

    Yes, 10x16 capacitors! The above picture uses 10x20capacitors, easy to find.
    Sorry -- the ATX conn is harder to rotate, need to keep the power traces as close to the output rails...

    Rotating the ATX connector is possible, but wll be a massacre...
    Keep in mind that M2-ATX am 'evolution' of M1-ATX. same footprint.
    This formfactor was 'imported' from Morex, which makes PSU boards with the same formfactor. I thought it is a good idea to keep the same dimensions for the M1-ATX and M2-ATX, since a lot of cases are made for these boards.

    Will the M2-ATX shutdown if it is overloaded?

    Yes!
    OverCurrent protection is set for the 5, 5VSB, 3.3 and 12V.
