Please review my PCB

Question

Hey guys, I am pretty new to this whole thing, but I’d like some input if possible. Can you tell me what I am immediately doing wrong? I’m sure there is plenty. I’m trying to keep all the components on one side, but let me know if that’s stupid. I really appreciate any input at all. 2024-08-06-160705_427x895_scrot427×895 97.3 KB 2024-08-06-160627_1167x763_scrot1167×763 105 KB

PMODE allows you to set the speed you want to communicate. Currently, it’s floating

Thanks so much! So can the green 3V3 is fine where it is running under the edge of the rj45 or is it safer to just run traces under there? I actully based this circuit partially off of this common W5500 module I pulled apart which appears to have them floating. I’ll connect them to ground since it seems like 10BT half-duplex is probably fine for the esp32 I’m using. image800×600 85.6 KB

Yes, that’s right. Exactly
