I want to build a computer for my car. For that I want to construct an enclosure in head unit size (Single http://en.wikipedia.org/wiki/ISO_7736 DIN ISO 7736 (178x53 mm)).
For this purpose I find the DN2800MT seems to fit perfectly, but I have some issues with the power supply: The battery can't supply 12V at all the time. For other (older) boards, there are dc-dc-converters to plug in directly into the ATX-connector on these boards, which solve this problem. But the DN2800MT seems not to have an ATX-connector, just the dc/in-jack and the 1x2pin internal connector.
Is there a possibility to use this board in my car? Or would another board be the better solution?
According to the specs, the on-board header and the rear panel jack are 19v DC. Also, the board has the ATX12v and 2x2 CPU connections for a standard power supply. You can power the board from either.
According to the Technical Product Specs (http://downloadmirror.intel.com/20714/eng/DN2800MT_TechProdSpec01.pdf http://downloadmirror.intel.com/20714/eng/DN2800MT_TechProdSpec01.pdf, look for 2.2), there are neither ATX12v nor 2x2-CPU-Connectors? Or am I wrong?
The DN2800MT has an internal DC-to-DC circuit built in with wide-range input voltage support from 8V through 19V. We have heard of customers being able to power it up even with as little as 6V.
Well I'll be dang. You're right. I don't know what board I was looking at then. I should have saved the pdf. It was the exact same board except it clearly indicated ATX12 and 2x2 on-board connections in addition to the 8-19v connectors.
As far as putting it in a car, my concern would be the environment. Down here in South Texas the inside of a vehicle can easily hit 140 when parked in the sun. Humidity is another factor.
Well, i don't think the temperature is a big problem. Currently I am living in Germany, very moderate clima...
Humidity may be a problem though. But this applies also to head units or other electric stuff in cars. I'll give it a try!
