Looks like just a distribution board + fuses, right? Should be easy to create with EasyEDA. Maybe even based on my board so that there’s only one single.
Yes that’s right.
I need a similar system.
Even better if it’s on your board.
Your project match my needs for xlights show.
Feel free to copy my project and add the stuff around 
Do you need the fuses? That’s probably the hardest part: to find through-hole fuse holders for that 19mm car fuses. The design of the schematics and the PCB is easy, the basics can be learned within a few hours.
What currents do you expect? If it’s serveral amps, It would make sense to contact JLC support to ask what thinkness and width of copper is required.
Edit: not soo hard, just search for “fuse holder auto blade”, here are some: https://www.farnell.com/datasheets/1703971.pdf.
But I don’t think you can build the board cheaper that way. It’s available for $35 from china. The fuse holders alone costs $25 at farnell.
Yes I totally agree with you. Found this for 13€ https://fr.aliexpress.com/item/1005005971154210.html
Do you think it is easily possible to add an ethernet port on the board ?
What is the value of the resistors I should be using ? (R1-R8)
Depends on who you ask, you’ll get recommendations from 0 to 300 or more. Quindor has a pretty good write up here. Data Signal Cable Conditioning - quinled.info
Finally assembled and tested. Here goes the image of the finished board. Thanks everyone for the help.

Hi, this is nearly exactly that what I’m looking for - I start designing but thought: maybe look around a little bit. I have used some esp32 to flash the wled project, but I have no experiences with generating a pcb (last time was 30 years ago :-)).
And now my maybe a little bit stupid question: Is the Sound Reactive part include in the original files? Or do I need to modify the original files (I have never added sound to my wled, but maybe it is a nice idea).
The picture of Duttasagar looks perfekt to me. Which micro do you use?
Thanks
