@genmaicha ESP32 module is just for https://github.com/wled/WLED and the cap is on the 12v rail for the LED strips, there's a buck converter (the inductor is for that) to get 3.3v for the ESP (from either 12 or 5v USB) and there's a 5v reg + translator to get the LED data line bumped up from 3.3 to 5v
Plan is to have 3 of these on a network for DJ lights, one on each speaker and 1 on the table.
just the continuation of this: https://wizard.casa/post/019acdf0-3783-bce0-e37e-8b6c0ad169f3
I have no idea if it'll be simple to control 3 with the same sort of setup 🤞
