Noob questions about wiring

Thank you very much for your quick reply!

I have made a quick diagram to show the setup i am trying to build.

  • The power supply is fused (is this the fuse we are talking about?)
  • How can i calculate the wire size from psu to led strip ( lenght=3,5 at max )
  • Led strip is the WS2812b
  • Amp calculation if i am right: 288 leds x 0,06a = 17,28A

I do not know if and where i should place a level shifter?

I don’t know what this is and it seems a bit to advanced for me.

I hope this helps in what i am trying to build.
