As you'd expect, the new board remains compatible with all the existing Pi 3 Model B accessories and retains the $35 price point.
"Achieving reliable wireless connectivity in crowded airwaves is a foremost concern for developers of industrial IoT and smart home systems, which lead us to select Cypress' 802.11ac combo SoC for the Raspberry Pi 3 Model B+ board", said Eben Upton, CEO of Raspberry Pi Trading. The B+ has the same quad-core, but there is a 15% increase, up to 1.4 GHz, which means a better performance for the latest model. Sadly, the module will need a tiny fan to keep things cool.
If you prefer wired to wireless, there's more good news.
Previous Raspberry Pi devices have used the LAN951x family of chips, which combine a USB hub and 10/100 Ethernet controller.
The wireless components offer a significant additional benefit. There's also a new PCB antenna similar to the one introduced on the cheaper Raspberry Pi Zero. The 3 B+ on the other hand, upgrades to the LAN7515 for Gigabit over USB 2.0 connectivity. And finally, the giant is coming up with the successor model of the PC with Raspberry Pi 3 Model B+ model. Power-over-Ethernet is now officially supported with a separate add-on.
As it was the case with previous Raspberry Pi models, the new Raspberry Pi 3 Model B+ is already available with the same USA $35/£32.00/€38,99 price tag. USB mass-storage booting has also been enhanced. First amongst these is the improved ARM Cortex-A53 processor.
The beefier processor benefits from power-related optimizations and a new heat spreader, which allowed for the higher clock speed to be reached.
Based on the same form-factor as earlier Raspberry Pi 2 and Raspberry Pi 3 models, that should make it compatible with all previously available cases, the new Raspberry Pi 3 Model B+ comes with plenty of improvements. The SBC is rated for 0 to 50°C temperatures. Audio/video connections include HDMI and MIPI DSI/CSI display/camera ports, as well as a four-pole stereo output and composite video port. The widely imitated 40-pin expansion header has not changed.
Raspberry Pi devices turn up all over the place, with sales fast approaching 20 million units. Mechanical drawings and schematics have already been posted.
