Well, unfortunate this thread lost interest. I just abandoned the PCB, and soldered components directly to the module like a savage. Either way, it works now. A shame the PCB mysteriously kills ESPs.

I would try soldering a wire from H1 PIn 1

I added ground wires from the regulator to various parts of the PCB, even to the ESP itself; unfortunately it had no effect on the system.

Yes, I am using a 3V3 programmer, but I have never connected my 3V3 lines, even on my working breadboard version. I have only ever connected my Rx, Tx, and GND lines to the programmer, and I've always been careful to connect the ground first to avoid chance of ESD damage. I started out by using an a...

Hmm yeah you have a good point, my ground situation could be better. Though, when watching it with an oscilloscope at the 3V3 pin on the ESP, there is no fluctuation whatsoever, sits at a steady 3.3V. Another factor is that I don't have brownout issues, even during wireless transmission. I'd be will...

Hey guys, I'm using a custom designed PCB for a project, but it seems I'm nearly killing every ESP32 module that is placed on there. The behaviour is extremely sporadic, but I'll do my best to explain everything in detail. Here is my schematic and PCB on Altium's online viewer. I can provide the fil...
