...I looked them up and they don't make a 3.5" 640x480 display...

Ah well, still worth a test though. Fingers crossed!

Hi, I have a screen to contribute! I brought this direct off china's taobao. for about US $8. I've been searching the forums but i can't find any information on how to convert this to 5V. Can someone help me? thanks.

I'm still not getting picture this is my second screen completely stumped. The screen turns darker so there is power and I tested it out it worked fully stock
Thanks in advance for your input

I have gone through 4 of these screens. 2 I got working by using a composite cable with the video signal line fully surrounded with the ground wire. Without this I could not get them to work. The other 2 are still a work in progress.

There was a fairly recent post with this same board. I don't think this will fit in a dmg without cutting off the adjustment buttons. I am not sure if this has been converted to 5v. I would start by poking around with a volt meter and seeing where there is 5v. I would start close to where the 12v source comes in and work out.
