This is my short list of Raspberry Pi links and notes for using this hardware
Raspberry Pi (The Original)
This was the first Raspberry Pi I used and installing the operating system is very straight forward. I have had issues with a few builds of Tumbleweed but they mostly work well. It is painfully obvious how under-powered this device is but it is fun to noodle around with it.
I have a project in the works I hope to complete fairly soon.
Raspberry Pi 2
I don’t have one of these but there are openSUSE images available
Raspberry Pi 3
I have played with this one the most and it works very well. I have a project in the works for this device.
