ESP32 GPIO pins info, restrictions and features

[wanek]

hi!

i’ve put together a new table for the ESP32, similar to the esp8266…

i’ve collected the info from various sources on the internet, there could be erroneous or missing information, so, please comment if something is off… check the links, there are lots of useful info and details
