Connecting LEDs to GPIO 14 & 15

Postby gb.123 » Thu May 20, 2021 10:05 pm

Hello !

I need a clarification :

I read somewhere that GPIO 14 & 15 are HIGH at boot time. What would happen if I attach LEDs to these ports ? Will it hamper the boot sequence or the the only side effect will be that LED will turn on while booting ? Will there be any other side effect ?

That should be fine; connecting anything there shouldn't have any negative effects for the ESP32.

Thanks so much !

PS: I was looking at ESP32-DevkitC V4 (Missed to mention that in my question so adding it now for everyone who reads this post in future)
