This came up on my radar, It is a new RBPi that fits in a standard hardware socket, I would be interesting to have an wifi module and printer board rolled into one PCB then install octoprint on the this the entire works in a very small footprint.
Thoughts, I am sure @Brook_Drumm and @foosel would be interested in the new pi.
