ESP32 Forum

I would like to make a small code example that would list hardware information of the ESP module.
For example amount of RAM, type of ram revision of CPU or peripherals, storage information, clock speed etc
I am not sure if device can report status of the battery
Are there any examples, snippets or particular functions?

Thanks
