ESP32-S2-WROVER usable pins without any trouble
Posted: Wed Oct 23, 2024 11:27 am
Hi to all the forum, i'm new in this world of ESP32 forum.
I use the ESP32 chip for several months, and I always seen https://randomnerdtutorials.com/esp32-p ... nce-gpios/ this topic for GPIO informations about use and refer.
At this moment, I want to study exactly what pins I can use in this board, in order to have a fully functional PCBs for all my project without any GPIO problems.
So, the only thing that I know is:
- That GPIO46 is for input only;
- That GPIO26 to GPIO32 are for flash and external ram and it's not recommended our use, but I directly don't have this pin on the PCB design so it's not a problem (except for GPIO26 that I have in the design, but I can simply don't use them);
- That GPIO connected to ADC2 is not recommended to use with PWM funcion or analog function, if there are the WiFi functions used.
I know only this information: I'm here to ask you a big help, telling me if the informations written are correct or not, if for this specific module there are other GPIO not usable, or other
Thanks a lot!
