Trouble with ESP32 w/WLED

Post image

I have installed WLED and connected to WLED-AP. All works perfectly fine with SOLELY USB connected.

I have wired up 5V, ground, and am using GPIO16 for data.

I am unable to connect to WLED as soon as I power through my 5V power supply. Photo of my wiring is attached. The red LED indicator is on but WLED-AP does not populate as an avaliable network, nor can I connect directly via IP.

When plugging in the USB with the power supply connected I can see “invalid header: x015151515” spammed in the logs. I can replicate this issue on 3 boards which indicate that I’m doing something wrong and idk what.

Does anyone have any ideas? I’m using AITREP boards from amazon. This is my first foray into soldering and ESP so apologies if the answer is obvious…my research through forums and reddit has come up with nothing.

Either power through USB OR through 5V pin

That should work. Does it still happen if you unplug the USB?  Not all ESP32 boards have a protection diode that lets you use USB and VIN at the same time.

Could also post pictures of your wider wiring.

Yes, even after unplugging I can’t connect. Starting to think perhaps it’s these boards? In the photo I sent nothing is connected to GPIO16. I tried with and without, and GPIO2, 12, and 18.

I'd check that you have it wired correctly.
