i use a ws2812b ledstrip and power it with 5V..but the data signal comes from an esp32 (3.3v)..it works fine.but i would like to know if i can also power the ws2812b ledstrip with 3.3V (its more convenient for my battery powered project). will it work and be safe long term? (datasheet says 3.5-5.3V power supply)
The controller is outside spec already at 3.3V, so maybe the whole thing will stop working at some point.
do you suggest any low power 5V buck converter? Level shifter looks, is not in need..
