Hey ya'll. Just wondering if anyone could help me figure out how to convert this LCD to 5v and trim it down.(Maybe take off the lcd controls) so that it'll fit in the dmg case. Thanks in advance! =)

I got the same board in a ebay backup camera. It was very difficult to fit inside the gameboy shell but can be done.

I started by dremeling down the sides of the board as close as i could to the surface mount components without damaging them. You will notice i did grind through a couple of traces on the back of the board. Everything seemd to still work including the buttons so i went ahead and desolderd them.

The board still wouldnt fit so i had to extensivly dremel out the inside of the shell. This is where things get abit ugly, its very easy to heat the dremel bit up too much and end up melting through the side of the shell. In my case i rushed it and the shell shows a few blemishes on the outside.

As for the 5v conversion i solderd the 5v input directly onto the regulator pin shown in the above pic. It helped the screen flicker alot but wasnt completly fixed, thats as far as i got. Hope this helps!

Thank you kind sir. You are "Da Real MVP" I had done some research on the AMS1117 and I was pretty sure that's where I needed to go. But you confirmed it for me. Haha

I can't see your wiring because of cable jam, but is the red wire sold directly on the board and then you made a bridge to the AMS1117, or is the red wire directly from the power supply to the AMS1117 ? Thanks ! ;)

Sorry. Red wire is directly on the board. Then to pin 3 on the AMS1117 chip. Also dont mind the shoddy soldering. I have to get a new tip.
