Im searching a schematic for the ESP32 or 12F that powers the WS2815 suffienciently. My previous attempts failed miserably because the AMS1117 3.3 on the dev board is like a nuclear reactor at 12v and gets destroyed.
You don’t power WS2815 from an ESP32. If you want to power the ESP from the same 12v power supply as the WS2815, you generally will need a 12v->5v buck converter as the boards generally have a max input voltage of 5.5-6V.
I know that I can’t power the ws2815 via the esp32, my current setup is an esp32 with buck converter due to the overheating of the ams1117 3.3
It’s all assembled on a perf board like an amateur.
I once tried my own PCB but it didn’t worked for some reason
Is there some schematic existing for esp32/12f with a buck converter?
Also when do I need a level shifter? I’m currently driving the LEDs directly by pin, it works pretty good, but it’s only a very short distance. I’ve also had in the past some builds with floating issues. One time I know was due to messing up one level shifter.
I know I need Common ground, but I’m searching for a schematic with buck converter and levelshifter, so I can solder a barebone esp12f/32 onto it. I want it to be small and reliable, my current setups aren’t that great. They improved, but a custom PCB would be nicer. Is there something, or do I have to make my own?
