Re: [GUIDE] 3.5 inch HDMI Display - high energy usage

There is a great guide from ZeroBoy about how to modify the display to fit into the original Game Boy case: https://www.zeroboy.eu/3-5-hdmi-touch-tft/ .

The 1.8V is for the central display controller RTD2660. One of the 3.3V is for the LCD and it's backlight. The other one seems to supply the...

I had them even closer together on my first case (the black one): 1.jpg The closeup photo in my first post of the shoulder button PC...

daddelkischde AIO PCB

Today I'd like to show you my first Game Boy Zero which I built with a PCB my friend Chris designed (and I reviewed): daddelkischde. The name is German in a southern dialect and not easy to translate. "Play box" could fit :geek: When Chris showed me some Game Boy Zeros last October on the net, I was...
