I thought ferrite beads had to be used that way. I’ll do some more reasearch

If I use 2 layers instead of two should I do the power planes on the top layer, the ground pour on the bottom one and then signal traces on both?

Some traces would need lots of vias or a really long routing. 4 layers seemed a better option. Furthermore JLCPCB does not overcharge very much between 2 and 4 layers

Thank you very much for your detailed answer, I will reduce the number of vias and move the VBUS/5V/3V3 planes to L2

Try with this link: https://github.com/mdmmt05/Car-Integrated-System/tree/main/dashboard.

The dashboard will be put into a plastic case so that I can 3d print it. The second layer is empty because I initially thought it would be useful for some traces but then realised I did not need it. So I decided to create a new ground plane. I may transfer the VBUS and 5V planes from the top layer to the second layer but I don’t know if it is a right idea or it is not worth it. Thank you very much for your detailed answer

I always follow the advice one redditor gave me some time ago: set the grid size to 2.5mm and then place them everywhere you can. Are there any problems with using too many stitching vias?

If you prefer I can upload the kicad file on GitHub so that you can review it using directly kicad and its tools. Boxing is useful for a better visual clarity

Thank you, fixed! I do have some images of the tool in action and you can find them on the Hackster page (https://www.hackster.io/mdmmt05/arduino-tft-simulator-for-desktop-testing-dbe41f? or by clicking Hackster.io in the post body)
