Hi evebody,
What are the pins of the ESP32 Dev Kit that we can use internal Pullup and/or Pulldown resistors?
I know that not all pins can be used for pull up and/or pulldown, but I would like to know what they are.
Thanks

Hi Sergio, welcome to the forum!

GPIO pins 34-39 (input only) do not have internal pull-up or pull-down resistors.

See https://www.espressif.com/sites/default ... eet_en.pdf, Appendix A – ESP32 Pin Lists A.1. Notes on ESP32 Pin Lists.
