Breezy4Pi was developed on Rapsberry Pi 2 model B to take advantage of its native advances in computing power, i.e. 1GB of internal RAM and a quad core processor in order to host a web server and to be able to have decent response times. It may be possible for someone to run Breezy4Pi on an older revision of the Pi, however I leave that as an exercise for the brave.
