LED ON on ESP32-S3-DevKitC-1 board

Postby Yohani » Thu Jan 25, 2024 4:53 pm

Hello.

I am using the ESP32-S3-DevKitC-1 board, but apparently I connected something wrong or some statement, since the LED that comes on the board turns on white, sometimes at the beginning it turns green.
What could be the problem?
It is worth mentioning that I have it mounted on a PCB, so it is difficult for me to do tests by disconnecting cables.

I hope you can help me, thank you very much.

That RGB LED is hooked to GPIO38. What are you doing with GPIO38?

Yes, this LED is connected to GPIO 38, but I am not using the pin.

I was testing the pins one by one and the problem was pin 48, but I don't know why.
