I'm currently running into a rather confusing problem...
I'm trying to power a strip of 60 WS2812 Leds and an NodeMcu/ESP8266 board.
The supply I chose is a 5V/4A supply.
This one to be precise: Meanwell GST25e05-P1J
I got myself some sockets to connect the supply to my circuit.
I already built a similar project here and it works flawlessly.
But in my current project I just can't seem to power the LEDs with that supply. I already tested it on the other circuit and there it works. So it isn't faulty.
But then when I power the current project with the USB from the NodeMcu-Board or with this 5V/10A power supply it works as intended.
I also ordered another batch of power supplies using the same connector but they also don't work.
So I rebuilt the whole circuit on a breadboard and used another of the sockets I had to power it with the same supply and it works without any problems.
So I thought it might be a problem with the socket I built into my case. But when I soldered another socket in there I still get the same result. It just doesn't seem to work.
I will attach a poorly drawn circuit diagram and a picture of the circuit in its case. (Yes I know it's ugly :/)
Is there anything I can do to fix that? I just can't think of any other reason why this should not work. Especially when everything works fine when I don't use the socket i added.
I already measured the voltage with an oscilloscope but it seems stable to me. So no drop because of the load or any weird interference on the output.
I really need help here :/
If you need any other info or better clarification or whatnot please tell me and I will try to update as soon as possible.
Or if you know a better place to ask this I also welcome any suggestion on that part :)
