Note: This is a great information site for ESP32 : https://randomnerdtutorials.com/projects-esp32/

For one year I have been playing around and created projects with the ESP32 (DOIT DevKit). As I played, tested and learned I wrote down all bits and bytes found in Internet. I reorganised that information is a more coherent and meaningfull way. Below you find the result of it, so far.
Note: If you see incorrectly information to your finds, please let me know
