I am sorry a new-be here. I am trying to learn this non Pi OS and the difference between the old GPIO and the newer preferred way of using the GPIO pins. Please provide a cheat sheet on all the overlays for the Le Potato and what they are used for. I have figured out what to use to see and use the i2c bus and the uuata but not the rest of the list. I have installed the wring tool but need to know what each overlay is and how to use it better then what I have found so far.
