The Raspberry Pi 3 B+ is the latest product in the Raspberry Pi 3 range boasting a 64-bit quad core processor running at 1.4GHz, dual-band 2.4GHz and 5GHz wireless LAN, Bluetooth 4.2/BLE, faster Ethernet, and PoE capability via a separate PoE HAT. The dual-band wireless LAN comes with modular compliance certification, allowing the board to be designed into end products with significantly reduced, wireless LAN compliance testing,improving both cost and time to market. 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.

Note: 

• Always use original Class 10 Micro SD card such as SANDISK ULTRA A1: 98MB/s microSD UHS-I CARD with Raspberry Pi 3 Model B+, Class 4 Card will not even boot your Pi up.
• Do not use the Raspberry Pi 3 Model B+ without case / enclosure as 3.3v on board supply is not regulated and a minute short of 3.3v line to ground will result in permanent damage to your Pi. Buy Raspberry Pi Official Case here.
