Newbie: I baught a ESP32 with a weird pin layout. How to identify GPxx pins?
Posted: Thu May 16, 2024 4:49 pm
Hello everyone,
this is my first time working with an ESP32. But I have some Arduino experience.
I baught an ESP32-WROOM-32D and now I try to find documentation to the pin layout but cant find it (I didnt know there are SO MANY different versions).
My plan is to follow a tutorial to connect a round display (GC9A01) with the ESP32, because my Arduino is so slow and has not enough memory for bigger pictures.

https://www.aliexpress.com/item/1005006 ... pt=glo2deu this is the ESP i baught
My problem is, that I cant find the following GP Pins, because my ESP only has "Dxx" Pins and i cant find good documentation about it.
How can I identify the following pins?
GP23
GP18
GP22
GP16
GP4
The only pins I can identify are the GND and 3v3 ones
Thank you for helping!!
