Default Anybody know about this new Board for CarPc

Hello, came across this new motherboard, which can be ideal for carpc with dual monitors. Intel D945GSEJT

Anybody familiar with it or used it ?

Seems it also has a 12v input, so no need for a custom car supply.

What do you think ?

Any idea on availability, price etc ?

D945GSEJT, requires 12V regulated. In case you want to use it for car PC applications, don't feed it with the car's power supply, you will damage the board.

It will however work when powered using a PSU like M2-ATX

You can use something like MC78T12 Regulator to regulate 12V but it will still be only at 3A, anything more and you risk burning out the board.

I would rather suggest Eeepc701 with car charger and you can mod it internally to add GPS/Bluetooth/anything over internal USB.

I got a similar system running, but i also added a touchscreen overlay to eeepc701.

Cheers

Are you sure? Unfortunately data sheets nowadays don't mention voltage tolerance on the DC voltage line.

If you consider ripple, switching wall-chargers have much less ripple, but may not have good voltage regulation (holding voltage steady at different currents).

I was expecting this board to have it's own switch-mode unit on-board (to generate 5V, etc.). If so, almost any such DC-DC converter unit can take +/-20% on the 12V line - just about the same as on the battery line in a car.

not sure about the above board but if you are looking for a nice mboard for a carpc, have a look at Zotac IONITX-L-E. It should serve as a great board. You can look up Zotac's India resellers @ ZOTAC India

As for the power supply, you'd find quite a variety @ mp3car...not sure about their availability in India.

Car voltage fluctuates very heavily during cranks, etc so never connect any motherboard directly.
Also a good PSU offers much more than just simple power regulation. I think it is very important part of any CarPC and must not be skipped!!!

Don't try to use ATX power supplies. I had a bad experience with one and I blew my car's alternator. Prefer to use a PICO board always with a BTX power supply which should not draw more than 80W. In case you are gonna use subs and other bigger rear speakers like JBL limiteds then I would recommend installing a Capacitor to regulate power voltage.
