There are numerous serious problems with this PCB. Even skimming the data sheets or design guides for the ESP32 or LDO would reveal them.
I’m puzzled why the post calls it “surprisingly good” when it’s so bad and missing basic requirements for different parts. I guess it’s surprising that anything at all was produced, but it’s weird that the author can’t identify the basic problems with the design.
This is similar to situations where someone uses an LLM to vibe code an app until it kind of works, but then an experienced developer takes one look at the codebase and can immediately see it was not developed with any understanding of the code.
