Beginner ask for review - Handheld "computer"

Hi,

I am working on my “computer”, and I’d like to hear some educated opinion about my schematics and layout.

It supposed to be a sandwich-solution with some buttons, a pot, an encoder, a mic a speaker and a display + some mosfet controlled terminals.

The RP2350 board have an own USB port and my board also have one, I am unsure how to make sure nothing blows up.
