Could use q 2.8 or 2.4, or the standard 3.5 composite / 3.2 spi and scale it down with overscan
Don't do I need some GPIO pins for the audio?

Yes, for pwm or i2s, don't see how that's related here.

I got my BW screen today... Didn't even look at the box before I opened the case. I don't think I will be able to use it on my upcoming gameboy zero build, since they sent me what looks like the 5" version. Does anyone have experience with this screen?

I got three of those today :evil: :evil: :evil:
So mad at Amazon. If you look at the label on the box it says 3.5” but the box itself lists sizes 3.5-5” super sucky situation.

Looking to wire up a screen like this one -
https://s.click.aliexpress.com/e/bRyCEHVQ

This is the same screen that is being used in the pocket Pi FE. I just want to use it without any aio board.

I guess I need a breakout or driver board?

Advice? Resources?

Everything I seem to find is referring to the ILI9341.

Thanks!

Hey you are in luck, I have a breakout for this LCD on my GitHub.

Hi all,

I don´t know if this is the right thread (please move if not), but I wanted to share what can become a very long term project of mine.
I´ve been always attracted by the idea of building a GBZ pocket myself, but when I look at the screens, they either have the wrong aspect ratio, or the resulting image size is too small when doing pixel perfect scaling (compared with the original GB screens). But, inspired by this RetroBerry project https://www.youtube.com/watch?v=BD4VzQpUiqg, I took a look at the square screens from Blackberry, and found the Q10 has a 720x720 screen that gives the same size of the GBP when scaling 3x
Image
One of my first ideas was to fit a whole Q10 inside a GBP shell (keyboard almost matches the buttons required for DMG/GBC color)
Image
But the problem is that the software support is a bit lacking (BB10 + Retroarch is already a bit outdated).
So, next thing could be to either connect the Q10 screen to the original GBC hardware (seriously), or better yet, connect it to the Pi Zero (also seriously).

As said before, this can turn into a very long term project of mine, and maybe Nintendo comes with a GB Classic in the meantime, but I'm decided to learn everything required.

here´s another great hdmi display which can be found on ali express....

https://de.aliexpress.com/item/3-5-zoll ... 2d7bd9aa0d

It fit´s perfect in the original DMG01 case. It runs at 5V, so no mod is needed.

One way could be:
-power the board by 12V.
-measure on which inductor you get 5V to ground.
-one this point you inject your 5V finally.
