Hello!
I hope that I am in the right forum. I want to power 3 LEDs of a WS2812b. I would try to power them with the NodeMCU board as I don't have a external power supply. Every LED needs at max. brightness 60mA. What is the output of that Vin Pin? I tried to search the internet, but I didn't find some usefull information as I don't really know what I have to look for. Now I've read that the USB-Port e.g. delivers about 660mA so I should be able to power about 10 LEDs but is that right?
Thank you
