ESP32 open drain outputs Q&A Forum › Category: ESP32 › ESP32 open drain outputs 0 Vote Up Vote Down lubond asked 6 months ago I need an open drain output pin to ground additional resistor in my voltage divider circuit. Is possible to use any output pin in ESP32? I think that all I have to do is to disable internal pull-up & pull-down, is it right?
