Fortunately, it has inherited the size and format of its predecessors, so (almost) all hats, boxes and accessories for the 3B also fit it.
The changes we see mainly in the new processor clocked at 1.4GHz, upgraded network connections and the possibility of power supply via the network port, Power over Ethernet or PoE (requires PoE module). The wireless network operates at both 2.4 and 5GHz and is now modularly certified, simplifying testing and certification for end products that integrate Raspberry Pi.
