the board is to wide to fit inside the GB case

@majestic Unfortunately, I think he's right. There's a similar-sized board that can be cut down to fit, but your variant appears to have quite a bit of circuitry on the parts of the board that you'd need to chop off.

I had the same board in my LCD.

I chopped it down as far as I could, but when I tried to see if it worked, all I got was a white screen (just the backlight I assume).

Something New...

http://www.ebay.com/itm/351913962824

I'm waiting on mine to confirm, but in reading the description and How-To document linked in the auction:

• It pulls power directly from a dedicated MicroUSB input and supplies the Pi through the header
• It gets image and sound data from HDMI (mini HDMI adapter required for the Pi Zero)
• It provides audio out via a headphone jack
• It has a GPIO connection for the touch interface that I'm assuming can be ignored/removed
• It includes a power switch, though I'm assuming it's not a safe shutdown switch
• It's only $25

The benefits seem pretty amazing, including pulling audio directly from HDMI on a zero and having passthrough 5v power natively.

When are you expecting to get this? I'm starting to look at displays to find which one I want to order, and this one is intriguing. Would love to know how well it works out.

Thanks for your time guys. Much appreciated. Guess i need to buy yet another screen. Yikes. Santa better turn up this year!

Hold up mate, I have the same board. I'm fairly sure it can be cut down. let me take a look at mine...
It can definitely run on 5v. but just be careful, my ribbon cable was only two thirds the width of the connector (top quality tech hey?), i plugged it back in wrong and blew the back-light driver circuitry.

Ok i had a look at my board. You could cut along the red line, to retain your screen settings buttons, you would need to run some wires to re-connect that one trace and the ground plane. The screen settings circuits the majority of these boards use is quite simple, they just involve grounding a pin on the main ic via a series of dropper resistors, each switch has a different value resistor across it.

On the rear of the board there are a couple of traces that you will see route the whole way around the outside, you could just run a jumper across the back of the board to re-connect those.

Failing all that, you could just save the screen and board, and use it in a GBA chassis. or try to use the slack in the ribbon cable to rotate the board 90 degrees.

Hope that helps.

Ate you able to show me pictures of the cut down and voltage change please?

[majestic]

Cant wait to try after work amazing help. Thanks

@RogerX

The screens I've seen that look similar to the one you've found were 88mm wide which meant they wouldn't fit in a gameboy housing. Please let us know if yours fits though as that may be a good find.

I dont know what ive done but i cannot get a picture from it after the cutdown. Also, cant remember which side to allign the ribbon cable. Id a oid this board if at all possible guys. Total nightmare
