Raspberry Pi is going through physical changes
| The Older Raspberry Pi 3 Model B+ | The NEW Raspberry Pi 4 Model B |
|---|---|
 |  |
| So what has changed? | New USB 3 Ports and the (Now Gigabit) Ethernet Port has changed sides! |
 |  |
| Micro USB and Full Size HDMI | Dual Micro-HDMI and USB-C Type |
Will my old case fit the New Raspberry Pi 4?
Fairly unlikely that your old case will fit and if it does It likely wont have I/O holes in the right places for the new Micro HDMI, USB 3, USB C and Ethernet
Will I need a new charger for the Raspberry Pi 4?
Yes. This one swap is the greatest positive, you are now less constrained and less likely to get "Brown Outs" caused by power hungry peripherals.
Will my GPIO Hat work on the new Raspberry Pi?
Very Likely! The Raspberry Pi 40Pin GPIO is built to be backwards compatible! You can double-check this here: Raspberry Pi 4 Model B Default GPIO Pinout with PoE Header
Will I need a new version of the PoE hat?
No, the PoE HAT designed for the Raspberry Pi 3 Model B+ is fully compatible with the Raspberry Pi 4 Model B.

Oh. my!
Looks like the 2Gb and above use a USB-C power adapter so a new power source will be required for these. The ethernet port location swap and dual HDMI will result in new cases being released for…
Hi!
Maybe it's worth adding a fan and heatsinks to this list. Here's some suggestions:
Ceramic heatsink for the CPU, 15x15x2mm: MPC151525TMPC151525T
Ceramic heatsink for the RAM, 10x10x2mm: MPC10…
No fair, after reading your post I now feel I am forced to apply for the RoadTest the Raspberry Pi 4 Model B (2GB) so I can experience all the new changes for myself. Great post, thanks.
