| Sep 22, 2022 at 17:29 | comment | added | Kuba hasn't forgotten Monica | This layout has approximately 0 chance of working right. You need a ground plane. Route all the traces on the bottom, make top layer the ground plane. You can use vias and short "jumpers" for the bottom layer signals in the ground plane, but that's about it. The long thin traces will cause this thing to self-destruct in short order, and it'll be an EMI nightmare as well. | |

| Sep 22, 2022 at 16:06 | comment | added | Kartman | Spend some more time with your schematic to make it more readable. I can’t make sense of +VSW and -VSW. Supposedly AC, but goes through 1K resistors to TR1. That does not look sensible. You confuse the mains earth with the gnd reference for the pico. As drawn, the pico is likely to vapourise. What is the ‘flyback’? There’s no reference to it in the schematic. There’s way to many defects. Concentrate on one section at a time and resolve those issues. You might want to look at control boards for washing machines or suchlike to see how they layout the circuit board. | |
