The Raspberry Pi model a+ is the perfect board for the minimalist pi fan. This pi uses the same processor as the model b+, but does away with the ethernet jack and three of the USB ports. This makes it lower power, less expensive and much lighter and smaller, it's still compatible with all pi operating systems and software, and has the exact same 40 pin gpio connector and camera/display sockets, so any hats or pi plates or other things that plug into the model b+ will work just the same.
