Powering ESP8266 from the LED PSU

Hello,

I am a total newbie, who tries to make things work for a big TV (85 inch). I am planning to use Wago connectors to connect 4 SK6812 strips between each other and to PSU and add ESP8266 with WLED to control them. My question is - can I cut a micro USB cable and connect 5V+ and GND to the LED PSU and plug micro-usb side directly into ESP’s usb port? So I can just use one pin for data? Thanks in advance!

Zitat von pclin

That should work, it doesn't really matter where the 5 V at the ESP USB port come from. But I would rather connect the USB cable to a USB port on the TV and connect 2 pins DATA and GND to the stripes.

Thank you. In Your suggested option, do I need to connect GND from each one of 4 strips? Or only one will be enough to establish common ground? Do I need some thicker wires or simple Duponts will be enough?

You got me thinking if my first plan was ok. Here is a little sketch - https://i.imgur.com/LBAvAIJ.png . Sorry for that mess, I tried my best. Of course there will be another terminal for GND, just like 5V+ wires. There will be about 370 LEDs, my initial plan was to feed power only from beginning of each strip, but according to calculations, in the end of 2.1 m. LED voltage will drop from 5 V to ~4.8 V. Too much.
