I was not so worried about a sub $100 price tag, as I am looking to have a project with my 2 boys. I read about the pi hat that is coming up… that is interesting! I currently have a pi 3b, pi 3b+, a bbb, and a few other types laying about. The pi4 and hat would be an exciting option, and tidy up the equipment bay. Any idea on when it may be released as this is the first I saw any information about it. I have several tech questions about it, but I am sure that info is not public yet!
