There is this one screen that is sold by this place called Dalian Good Display, and it has VGA. I was wondering how would I go about solder/wiring it to the Raspberry Pi ? And how would I be able to make it run off 5v? I doubt people would know much about that though, because I don't think anybody has used this screen before.

Here is the screen: http://www.buy-lcd.com/index.php?route= ... TT035KDH03

If you want to use VGA, you need to either get a 'micro hdmi to VGA' adapter (but let me stop you there, this WON'T work for 320x240 resolution, you will have to set 640x480 in config, which means you will have a blurry screen (as it will convert 640x480 to 320x240)). OR use something like the "gert666" which will convert the GPIOs into VGA (and you can set 320x240)..

For that LCD it's not worth it, it is 320x240.. if you're going to the trouble of hooking up VGA then get a 640x480 one.. FYI there is only one 640x480 panel available and it's not cheap https://www.aliexpress.com/item/new-ori ... 22384.html

If you really want to use that panel, use composite.

I think it should be obvious that the gert666 would not fit inside the case too. :/ I looked into it a while ago but it's not something that's viable since the higher resolution screen boards are already pushing the available space down to the absolute limit.

When I started out I was going to use VGA, I even ordered a PCB and the components but never actually built it:



If you think there is interest I could build a few. It's based on the original schematic but scaled WAY down and just solders to the top of the pi (zero or 3) without the headers (if possible to make it less tall). This would actually be perfect for the 640x480 board as the driver board accepts VGA.. so just 6x wires are needed..

I would be interested in a high res, VGA driver board to support 640x480 displays. What would a board like this cost?

Geh. You're killin' me here. I guess there's enough space for that...(maybe...)

Does it take up all of the GPIO? We still need pins for PWM and graceful shutdown afterall.

How would it interact with HDMI? If it can't be swapped between like it does with composite I probably wouldn't be interested even if I had the board in my hand this second. :/

It works in the exact same way as my DPI LCD board on my Super AIO which is why I didn't build this as dpi is better what that means is it is not plug and run like HDMI/composite.. There are free pins for pwm audio and shutdown.. Lookup gert666 dual monitor.. There is an app called gertcloner which looks like it might work.. Anything that works for the gert works for my DPI..

Ps this isn't a thread for an 'I want one of those' incase anyone feels like replying with that! Pm me instead. This is quite off topic from OPs post

I don't mind. But thanks for replying to my post anyways. I wasn't thinking that it would work very well either
