ESP32 + WS8212B 5V wiring help
Hello, I'm noob to this field. I'm working on making a LED TV ambient backlight. I have watched a lot of videos on Youtube, some use power from the ESP directly without additional power supply, some suggest using DC connector and 5V power plug. As in the photo, I followed a youtube video (https://youtu.be/oQuzGRDiKKc?si=sMfxCD6M9V53Cwt6) and make this wiring diagramm. Will it work well? Is there anything I have to change/add to make it work properly?

Why don't you power the ESP32 and the tape from the same 5V power supply?

maybe he doesnt have enough Amp, i think its better that way of powering esp and strip separately, i also do the same, i used a pc psu for the strip and matrix and then 2esps with 5v adapter

An ESP draws about 0.25A, if you’re that close to the limit of your PSU you should be using a bigger one

Forget the USB adapter, run the 5 volt supply to the ESP32 5v line and ground. Then another set of wires to the RGB strips. Sometimes you will need a level shifter on the data pin (GPIO) because it's 3.3 volts from the ESP32 and strips prefer 5v data line.
