Maximum voltage supplied on a port set as output

Postby Ristridin » Sat May 25, 2019 8:02 am

I've 1 port set as output on the ESP32. On HIGH, there's 5V on the port .
It's working fine for several months now, but I'm wondering: what is the maximum voltage on a port set as output?
I can imagine that it should be 3.3 volts, but I can't find any (maximum) ratings.
