Question: Is the PCB needed?

[Henrique Cury]

I remember seeing your first itteration was just a Arduino. Do I need the PCB? Can I just solder directly into the arduino? Is there a way to make the arduino work with the ps5?

[Jacek Fedoryński]

This project is the PCB. You can make a Slimbox instead if you want.

There is no way to make an Arduino work with the PS5 that I know of. Apart from using an external adapter.
