I understand their are different manufacturers and all, but I was watching
Introduction to ESP32 - Getting Started
and find my board does not have a pin out for GPIO0. I tried another pin, but the switch part is not working. If a tutorial says to use a certain pin out, and your device/board doesn't have it, what do you use to determine an alternative? I am still learning, smiles.

@dzimmer57 what board do you have. GPIO0 is often connected to the BOOT button. NOT all esp32 boards have the same number of pins, the nerds recommend the ESP32 DEVKIT V1 DOIT board. This is a 36 pin board.
You can often use a different pin as long as it is in the same category and not a special purpose.
Most of us here look to the nerds from time to time, check out the esp32 pinout section.
