Here is what the new Raspberry Pi looks like :
The three most noticeable physical differences are :
The Pi 3 Model B+ technical specifications are shown below :
The most notable differences between the Pi 3B+ and the Pi 3B are
The heart of the Pi 3 B+ is the BCM2837B0 running with a clock speed of 1.4GHz. This is an improvement over the Pi 3’s 1.2GHz although the number of cores remains the same at 4.
The memory remains unchanged at 1GB.
The number of USB ports remains unchanged with 4 full-sized USB 2.0 ports on the right hand-side of the board.
The Ethernet port now support Gigabit network connections and this will be welcomed by many users who have been asking for this feature for years. The new model will also support power over Ethernet with some additional hardware. Due to limitations in the the implementation the speed is limited to 300Mbps.
However the overall network throughput is now apparently three time better which is good news for any application that needs to shift data including network storage devices or media centres.
The ceramic antenna has been replaced with a resonant cavity design as seen on the Pi Zero W.
Video output includes HDMI via a full-sized HDMI connector and composite video via the 4-pole 3.5mm jack.
Stereo audio is still available via the HDMI connector and 4-pole 3.5mm jack as in the Pi 3.
The power connector is still a microUSB socket. Power consumption is higher and estimates suggest it draws 170-200mA more than a Pi 3.
The physical size of the Pi 3 B+ remains unchanged with overall dimensions of 85mm x 56mm x 17mm.
The 40-pin header used in this model is identical to previous generations so should be compatible with all hardware that works with the A+,B+,Pi 2 and Pi 3.
