Lopy and Lopy4 Power-Up default GPIO states
Is this documented officially anywhere? I'm trying to find out the state of GPIOs on a cold start right before pin initialization.
@robert-hh Thanks for your reply. It actually helped a lot :)

@kavehoo Befor eany firmware starts, it is defined by the ESP32 itself. The information is in the data sheet: https://www.espressif.com/sites/default/files/documentation/esp32_datasheet_en.pdf
Most GPIO port should be input ports, with some of them strapped to Low or high (look at chapter 2.4).
