Hello, first time poster (and also no significant EE background, so bear with me).

After receiving a batch of bad USB C PD trigger boards, I decided that it would be better if I made some myself. The design is taken from the CH224K datasheet. However, I am not sure if

the schematic is correct
the PCB is well laid out (I really struggled to fit everything)

Here is the schematic, and here is the PCB. Both are in a Codeberg repo.

I tried to implement all of your suggestions. Would you mind having a look now?

Edit: BTW DRC passes (apart from an error with the thermal island in a GND copper zone and a lot of warnings about text size and thickness)
