The gpio map for the ESP32 PoE ISO board:

says "GPI34 is connected to button and has 10K pullup".

For clarity, does that mean I can connect an external button with one terminal to pin 34 and the other terminal to ground (without the need for a 10k resistor) and when I press the external button it will work (without damaging anything).


You can do that and you will have two buttons doing the same thing - the one you added and the on-board one.

Thanks - that is exactly what I want, the other is an external button mounted on a case.
