For several years I have been playing around and created projects with the Raspberry Pi. I started with the B, B+ to 2B, next 3B and currently 4B. I have also a Zero. 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Note: some documents might be outdated as I am busy with other stuff. If you see such a document or incorrectly information to your finds, please let me know
