Good morning. Could you help me identify which GPIO pins will serve as Pull_UP inputs? I want to use three pushbuttons without external resistors, so I need to know which pins are suitable for this. I have searched a lot in the documentations and via Google, other platforms and I have found absolutely nothing related to the topic.
I've always liked this summary: ESP32 Pinout Reference: Which GPIO pins should you use? | Random Nerd Tutorials
It's user friendly and comprehensive.
The 'correct' answer is as always to consult with the datasheet, but the link above is more accessible.
The way I found the above link (years ago already) was with this query:
https://www.google.com/search?q=esp32+which+pins+to+use
Sometimes, the most obvious approach really does work.
Thank you very much for your reply!
