ESP32-C3-DEVKIT-1 schematic

Is the RGB LED really running on 3.3V? The datasheet for SK68XXMINI-HS says 3.7V minimum.

Maybe it is hooked to 5V and the schematic is wrong? Or does this RGB LED really work on 3.3V?

I'll see if I can double-check, but yeah, it looks like that. From what I recall, it mostly affects the color purity (as the blue and green die can be underpowered) but aside from that doesn't really affect the functionality of the device... and as it's simply used as an indicator here, color purity isn't that important.

On a ESP32-C3-DevKitM-1 I measured 3.29 VDC
White looks a little blueish but they all do for me Edit: (all white LEDs look a little blue for me).
