The Raspberry Pi 3 Model B is the most popular Raspberry Pi computer made, and the Pi Foundation knows you can always make a good thing better! And what could make the Pi 3 better? How about a faster processor, 5 GHz WiFi, and updated Ethernet chip with PoE capability? Good guess – that’s exactly what they did!
The Raspberry Pi 3 Model B+ is the latest product in the Raspberry Pi 3 range, boasting an updated 64-bit quad core processor running at 1.4GHz with built-in metal heatsink, dual-band 2.4GHz and 5GHz wireless LAN, faster (300 mbps) Ethernet, and PoE capability via a separate PoE HAT.
The Raspberry Pi 3 Model B+ maintains the same mechanical footprint as both the Raspberry Pi 2 Model B and the Raspberry Pi 3 Model B. Adafruit made/brand cases will still fit but some other cases may not, especially ones that depend on component location or have a built in a heatsink.
You can still use all your favorite Raspbian or PIXEL software with this update – just make sure to upgrade your Raspbian operating system install so that the firmware can support the new chips.
The dual-band wireless LAN comes with modular compliance certification, that’s the metal tin in the corner of the Pi, with the logo stamped on it. This allows the board to be designed into end products with significantly reduced wireless LAN compliance testing, improving both cost and time to market.
