What's new with the Raspberry Pi 3 Model B+?

What's new with the Raspberry Pi 3 Model B+?

While the Raspberry Pi's birthday (and the traditional release date for the newest and best Pi) was a few weeks ago, Pi Day is a fitting enough date for the introduction of the best Pi to date.

There has been 19 million Raspberry Pis computers sold in total, and they can be found in schools, homes, offices and factories all over the globe.

THE RASPBERRY PI FOUNDATION has unveiled the Raspberry Pi 3 Model B+, its most powerful miniature PC yet. The first example was Raspberry Pi 1 Model B+, which added two additional USB ports, introduced our current form factor, and rolled up a variety of other feedback from the community.

A blog post reveals it is powered by a 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU, and connectivity wise it offers dual-band 802.11ac wireless LAN and Bluetooth 4.2, as well as faster Ethernet (Gigabit Ethernet over USB 2.0).

Lab tests show nearly a 25 percent performance improvement for 2.4 GHz bandwidth over the Model B. Bluetooth has also been updated to version 4.2 in place of 4.0. These include the new processor's improved power integrity, packaging, and heat spreader, and internal clocking and voltage rule tuning. The Raspberry Pi Foundation will be submitting the application to ICASA and approval is expected around May/June. It's certainly a nice aesthetic touch, but has also allowed the board to be FCC certified as a radio module, a move that should reduce future conformance testing costs.

Power management improvements allow the micro-computer to run at 1.4 GHz at lower temperatures, and when the temps rise above 70° C the frequency is reduced to 1.2 GHz and power consumption is dropped to extend the time before the 3B+ reaches an 80° C thermal throttle.

Wireless connectivity is also greatly improved thanks to the inclusion of a Cypress CYW43455 "combo" chip and a Proant PCB antenna, which is very similar to the one used on the Pi Zero W.

The Raspberry Pi 3 Model B+ is on sale now, and maintains the same price point at $35 (around £25, AU$45).

In short, the upgraded Pi promises more speed and power.
