yes I get it.... there is some saving grace in that these all have a polyfuse on them. but yes I get it.

What's going on with that layout? Only use 45° angles between traces and try to avoid unnecessary bends. The decoupling cap for U3 could also be closer. And having a good ground plane won't hurt.
If you want some inspiration for a robust Arduino, look there: https://www.rugged-circuits.com/microcontroller-boards/ruggeduino-et-extended-temperature-40c-85c

there is a huge ground plane for the cp2102, there are vias going to the bottom
