Does the ESP32-EVB have some LEDs that I can control ?

[GeorgeFlorian1]

Hello !

I've been looking at an ESP32-EVB for the past couple of days and there is a "big" LED on it named LED3, but that is an IR transmitter and I can't use it like a normal LED.

Does the board have some LEDs that I can control ?

I've been looking through documentation but I couldn't find a thing.
I've also looked at this: http://www.barth-dev.de/misc/eqipment/e ... b-pin-map/ .

The link you posted bring you to Olimex site. There you can find the schematic for the board.

I switched one on which also operated the relay to show when my software was running normally. The visual and audible confirmation was useful, but I chose not to send high frequency LED flashes on this pin on this board, but I was only using ESP32-EVB for initial testing.

I also did that, but the project I am working on uses those relays to control other hardware. So I can't use those anymore because I will compromise the functionality of the other hardware components.

Yes, and it did not help me.

Ok, well there are only 6 leds on that PCB.
