LED WS2815 ESP32-S3 drive
Hello, I wanted to drive two LED strips of WS2815 (each around 36 to 40pcs). I wanted to know if I can wire directly the GPIO output of the ESP32-S3 to the data input of the LED strips?

Given that the WS2815 require >= 9.5V VDD, and their logic high input is >= 0.7VDD, that's pretty much a "no".I wanted to know if I can wire directly the GPIO output of the ESP32-S3 to the data input of the [WS2815]

Turns out the datasheet is confusing, see e.g. here; the data streams use 5V logic levels. Still 0.7*5V=3.7V, so you need a 5V level shifter to drive the data signal for the LEDs.

Can't blame ya, honestly. I happened to go 'that can't be right' and Google around a bit and hit the link I posted, otherwise I'd come to the same conclusion as you. That datasheet is simply written wrong imo.
