Onboard LEDs Control

[i3creations]

Hi,

There are 2 leds on my ESP32 NodeMCU module. One of them is on digital pin 2. Another is unknown to me. It lights up red when I power on the module. I would like to be able to turn it on and off and possibly change the color as well.

Is this possible?

Thanks for your help!

Hi i3creations,

I guess the other LED is just indication that the 5V power supply is on.
This is at least what I see in the schematic of NodeMCU-32S.

If this is exact schematic of your very board, then you will not be able to turn it on and off and change the color.

That's all I need to know.

Thanks!
