The improved power integrity of the BCM2837B0 package, and the improved regulation accuracy of our new MaxLinear MxL7704 power management IC, have allowed us to tune our clocking and voltage rules for both better peak performance and longer-duration sustained performance.īelow 70☌, we use the improvements to increase the core frequency to 1.4GHz. Gordon has rolled up fixes for all known issues into the BCM2837B0 boot ROM, and PXE boot is now enabled by default. Testing it in the wild shook out a number of compatibility issues with particular switches and traffic environments. Raspberry Pi 3B was our first product to support PXE Ethernet boot. This has allowed us to certify the entire board as a radio module under FCC rules, which in turn will significantly reduce the cost of conformance testing Raspberry Pi-based products.Ĭoming soon to a Raspberry Pi 3B+ near you The wireless circuitry is encapsulated under a metal shield, rather fetchingly embossed with our logo. Compared to its predecessor, Raspberry Pi 3B+ delivers somewhat better performance in the 2.4GHz band, and far better performance in the 5GHz band, as demonstrated by these iperf results from LibreELEC developer Milhouse.

Together these allow us to reach higher clock frequencies (or to run at lower voltages to reduce power consumption), and to more accurately monitor and control the temperature of the chip.ĭual-band wireless LAN and Bluetooth are provided by the Cypress CYW43455 “combo” chip, connected to a Proant PCB antenna similar to the one used on Raspberry Pi Zero W. The new product is built around BCM2837B0, an updated version of the 64-bit Broadcom application processor used in Raspberry Pi 3B, which incorporates power integrity optimisations, and a heat spreader (that’s the shiny metal bit you can see in the photos). Here, he and I have a chat about what’s new. Roger Thornton did the design work on this revision of the Raspberry Pi. Raspberry Pi 3B+ is available to buy today from our network of Approved Resellers. Improved PXE network and USB mass-storage bootingĪlongside a 200MHz increase in peak CPU clock frequency, we have roughly three times the wired and wireless network throughput, and the ability to sustain high performance for much longer periods.Power-over-Ethernet support (with separate PoE HAT).Faster Ethernet (Gigabit Ethernet over USB 2.0).Dual-band 802.11ac wireless LAN and Bluetooth 4.2.A 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU.So, without further ado, Raspberry Pi 3 Model B+ is now on sale for $35 (the same price as the existing Raspberry Pi 3 Model B), featuring: Raspberry Pi 2 didn’t get this treatment, of course, as it was superseded after only one year but it feels like it’s high time that Raspberry Pi 3 received the “plus” treatment. 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. Those Raspberry Pi watchers will know that we have a history of releasing improved versions of our products a couple of years into their lives. Since then, we’ve sold over nine million Raspberry Pi 3 units (we’ve sold 19 million Raspberry Pis in total), which have been put to work in schools, homes, offices and factories all over the globe. This was our first 64-bit product, and our first product to feature integrated wireless connectivity. Just over two years ago, we released Raspberry Pi 3 Model B.

If you’ve been a Raspberry Pi watcher for a while now, you’ll have a bit of a feel for how we update our products. (We recommend the video anyway, even if you do have time for a long read. If you don’t have time to read it all, we recommend you watch this video, which will fill you in with everything you need, and then head straight to the product page to fill yer boots.
