After discovering the motherboard of the AMD Ryzen 7 7840 series from Framework, I said to myself that it was, for me, the ideal platform to make a handled version.
I was able to see various interesting projects, but all of them used USB C ports as an interface for the display. 
I said to myself that will be smart to use the motherboard's eDP ports for this type of project, since Framework provides all the information necessary for its use.

So I started researching how to use this eDP port. I noticed that there were not many different screen models and came across the screen models intended in particular for the ROG Ally, Lenovo Legion Go.... which are either 7" 1920x1080@120hz. TL070FVXS01-02, ZS070FHT-L41 or 8" 1920x1200@120hz NS080WUM-LX1
I had to look for the documentation for these screens to get the pinout, I only found it for the TL070FVXS01-02.
I also started drawing mechanical elements to print in 3D.

My project is also to have modular controllers, i would like to integrate a mini trackball, like 

I would like to use internal mother board connectors to let USB C accessible to external stuffs'.
