Hi
I have one dev. kit labeled ESP32-S3-CAM N16R8 re 1.3
On the board there is a little LED about 2x2 mm white square, close right to two small LEDs, close pins on the right, above boot button
What is the corresponding GPIO number ? is it a three color LED ?

Maybe
this will help. (Indicates a white LED @ GPIO 48.)

It could also be a WS2812-type RGB LED. Maybe give that a try.

Hi I don't think so
A LED WS2812 is measuring 5x5 mm
The LED on my ESP32-S3-CAM is clearly smaller (about 2x 2 mm)

It shouldn't be too hard to find, assuming it is connected to gpio.

I have tried all the GPIO : (0 ... 21, 35 ... 42, 45, 47, 48) on my kit ESP32‑S3‑CAM UICPAL N16R8
No success
Conclusion : the small LED is probably not available for piloting
