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

  1. the schematic is correct
  2. 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.

    That’s an AMAZING comment, thank you so much!

    Re: schematics. Will take this in consideration next time

    Re: constraints and DRC. I haven’t done this yet because I’m really scared of the result (actually, I ran DRC and it gave me minor things). I didn’t want to invest too much time in something I didn’t know if it would work

    Re: silkscreen. I placed designators there for space reasons, I will try and see if they would fit if smaller. Also, metadata in the silkscreen seems a good idea.

    Re: U1. I was worried that moving the IC would mean rerouting everything. I noticed and thought “too bad”, but I will try this

    Re: SMD handsoldering. I never tried this before, so I figured that for me 1206 would be a good place to start. 0603 would not be comfortable 😆, I envy your colleague

    Re: C1. Will do!

    Re: CC resistors. It’s a great idea!

    Edit: a hot plate would be needed for the CH224, right? Or I could try PCBA and go for 0603s

    Edit 2: So it is fine to use vias to connect those two ground planes this way?
