GPIO output low internal resistor

[Reiner1210]

Hello,

when I set a GPIO as output and it is set low. Is this a real GND or tristate.
So the question is can flow a current over this pin ? And if yes how much is the internal resistor ?

By the way: Is it possible to set pullup resistors on outputs or is this ignored ?

Not all GPIOs on an ESP32 have pullup and pulldown resistors.
Take a look at the data sheet. All your questions are answered there.
