$35 Raspberry Pi 3 Model B+ Launched with a Faster Processor, 802.11ac WiFi, Gigabit Ethernet, and Optional PoE

The Raspberry Pi Foundation has just introduced a updated version of their popular Raspberry Pi 3 Model B board with a Model B+ that increases the processor clocked up to 1.4 GHz, adds dual-band 802.11ac WiFi, and Bluetooth 4.2, Gigabit Ethernet (via USB 2.0 to Ethernet bridge), as well as support for PoE (Power-over-Ethernet) via an external HAT add-on board.

Raspberry Pi 3B+ specifications:

  • SoC – Broadcom BCM2837B0 64-bit ARMv8 quad core Cortex A53 processor @ 1.4GHz with dual core VideoCore IV GPU
  • System Memory – 1GB LPDDR2
  • Storage – micro SD slot
  • Video & Audio Output – HDMI 1.4 and 4-pole stereo audio and composite video port
  • Connectivity – Gigabit Ethernet (via Microchip LAN7515 USB 2.0 to GbE bridge), maximum throughput 300 Mbps), WiFi 802.11 b/g/n/ac and Bluetooth 4.2 LE (via Cypress CYW43455 based module)
  • USB – 4x USB 2.0 host ports, 1x micro USB port for power
  • Expansion
    • 40-pin GPIO header
    • MIPI DSI for Raspberry Pi touch screen display
    • MIPI CSI for Raspberry Pi camera
  • Power Supply
    • 5V up to 2.4A via micro USB port
    • PoE via HAT board
  • Dimensions – 85 x 56 x 17 mm

The new Raspberry Pi board is said to improve PXE network and USB mass-storage booting, as well as thermal management thanks to a heat spreader placed on top of BCM2837B0 SoC.

Optional (and upcoming) PoE HAT

Since they’ve only done a few tweaks, software support will remain the same with NOOBS, Raspbian, and the many other available distributions.

The Raspberry Pi 3 Model B+ is now sold for $35 on Element14 or RS Components, and will remain in production until at least January 2023. The PoE HAT is available on backorder for $20 with stock expected for April 9, at least on Newark.

Amazing. The RPI foundation keeps addressing the non-issues, while neglecting the actual issues.

So they added more high-speed interfaces to share the single USB 2.0 bus?

But it’s not 100% compatible across the different models though, since they moved from 32-bit to 64-bit with the RPi 3.
I think this is more of a ecosystem issue, i.e. housings, hats etc.

Dang, fanless aluminum case not supported, different layout for components.

2GB RAM + improved Micro SD card (faster write and reads by default) are missing 🙁

I’m not sure why they should upgrade to USB 3.1 when the SoC is stuck to one USB 2.0 for all the devices.

Exactly what I was thinking. I was really hoping for giga Ethernet, but instead it’s half-baked. I hope this is a stepping stone to the Pi4 with “proper (not shared)” giga Ethernet.

I don’t think RPF ever moved to 64bit — raspbian is the bastion of 32-bitness, and understandably so, given the amount of effort it would take the foundation to move to 64bit (VC-what?), and upgrade their boards to something above the gargantuan 1GB…

So disappointing, and this thingy suppose to last to 2020 or later… for the future release of the Pi 4 *cough cough*
By the look of things they might not even getting 2 GB RAM. More like 1.5GB RAM LPDDR2.

By the time they release that, most of the other chip maker will be on 4GB standard. And if you can spend $50 on top of the Pi 4. You can get something the Pi is getting in 10 years time. Like can run Windows.

Nice, so I were right back in January forecasting ‘most crappy Gigabit Ethernet’ ever implemented soon by RPi folks: https://forum.openmediavault.org/index.php/Thread/18991-New-approach-for-Raspberry-Pi-OMV-images/?postID=166467#post166467

Folks, please understand that all Raspberry Pi since the first one sold 6 years ago are all more or less the same. It’s an old an boring 32-bit processor called VideoCore IV that got one or more crappily integrated ARM cores to the die. All the limitations (only 1 x USB2, only 1 GB DDR2 and so on) are due to this and RPi Foundation can’t change that since they would loose their only asset: backwards compatibility.

Not easy. When they come up with a new SoC they loose backwards compatibility which none of their customers will be able to understand. They would either need new OS images or they can convince Broadcom to add the anachronistic VideoCore IV bootloader crap to a decent SoC design (which I doubt).

TLS : But it’s not 100% compatible across the different models though, since they moved from 32-bit to 64-bit with the RPi 3. Software wise it’s 100% compatible since they let the Cortex-A53 cores remain in 32-bit mode. And while a lot of people continually ask for 64-bit RPi support that’s both challenging on this platform (since the main CPU is the old and boring 32-bit VideoCore IV and not the ARM cores! No idea why no one wants to understand/accept this) and also somewhat stupid when the SoC is limited to laughable 1 GB DRAM (since 64-bit software eats… Read more »

What do you want to do with peripherals that are SuperSpeed capable if 1) the host is only capable of ultra slow ‘Hi-Speed’ and 2) all USB receptacles and the Ethernet chip have to share the horribly limited bandwidth of the one USB2 port?

The average RPi buyer is not *YOU* @tkaiser.

You’ve never understood or appreciated the market the RPi is aimed at, so why do you (and others of your ilk) routinely bore everyone to death with your SBC “insight” and demands that the RPi should be a frickin’ supercomputer for $35?

If the RPi (even this 3+) isn’t for you, why not just ignore it, eh? Your rants reveal you to be such a fanboi.

Depends always on the use case of course. If headless operation is an option you get both (and real Gigabit Ethernet + real SATA) on an EspressoBin for example. With ‘general purpose’ use cases in mind maybe one of the many (soon to be released) RK3399 boards fits your needs?

I fear that the addition of the new wifi module and the GbE PHY in the USB hub will make the power problems of the RPi even worse… also while before you had more or less no contention issues with the Ethernet on USB due to it’s low bandwidth, the network interface can now saturate the USB bus and if you have some storage class device attached – it will be probably worse than before if there is no traffic shaping for mass storage/ethernet…

manuti : @Mark Birss Maybe in Raspberry Pi 4 Why should they choose USB Ethernet in an upcoming incompatible RPi 4? If they will ever move away from a SoC designed in last decade (VideoCore IV) to one that has been designed in this decade then why should this new SoC be that limited as the VC4 is? If they switch to an incompatible modern SoC I would assume the feature list contains native Gigabit Ethernet, a memory controller capable to deal with more than 1 GB DRAM (DDR2) and everything else that’s more or less standard today on ARM… Read more »

As soon as the access patterns affect disk and network at the same time performance drops drastically compared to Fast Ethernet. This affects tasks like opening/closing small files as well as overall sequential write performance dropping from ~9MB/s with Fast Ethernet to lower numbers with GbE. Though as… Read more »

Why? You would need to increase input voltage maybe to even 6V to be able to feed that high amperage to an RPi: https://www.cnx-software.com/2017/12/05/libre-computer-renegade-sbc-features-rockchip-rk3328-processor-with-up-to-4gb-ddr4-ram-crowdfunding/#comment-549684

BTW: The Micro USB connector is still rated for 1.8A maximum (for a reason). I would fear to burn my fingers touching Micro USB jack or receptacle when trying to get 3A through those laughably tiny contacts 🙂

Headless for OpenWRT / Linux. Im looking at using CJDNS (either with SoC encryption support or for example a Silicom PESC62-RoHS Security Protocol Processor adapter – will need adapter to convert to PCI-E x4)

So will maybe try a Gemeni Lake X86 baord (NUC or Motherboard) also

So will look at the ESPRESSObin (it offers OpenWRT support)

Thank you for your recommendation

Mark Birss : SoC encryption support Well, the older RPi 3 does not support ARMv8 crypto extensions (AFAIK the only two 64-bit ARMv8 SoCs that miss this feature are Broadcom BCM2837 and Amlogic S905 on ODROID-C2 and NanoPi K2) which can have a huge impact on AES performance if this matters for you. Without those crypto extensions AES performance is magnitudes lower than with, see for example https://forum.armbian.com/topic/4583-rock64/?do=findComment&comment=37829 The SoC on the aforementioned EspressoBin supports both ARMv8 crypto extensions and an own Marvell proprietary ‘5Gbps Security Engine’ — mainline kernel support has been added recently and you find some information… Read more »

The other reason they do not change the SoC is that no other SBC builder can get the SoC. It ties, padlocks the buyers into RPI software, hardware and excludes competition. Other SBC maker have to use other SoC brands, designs. If I recall correct, the original SoC which inspired RPI is a media player SoC ( think Roku box or bottom end Now TV box , white original. Low specs). Hence the original was never designed with more than one USB in mind. Bits have been bolted on and parts tinkered with, hence it is a home brew monster… Read more »

@manuti The flirc case is a slightly tighter fit than before as the heat spreader adds about 0.5mm, but it fits. I’ve been using the Kodi case with a test sample for the last month.

@willy Yep – though the RPi foundation’s core aims are still education – not flogging hardware for profit. The Raspbian ecosystem with stuff like NOOBs etc. usually ‘just works’, and has a much better ‘novice experience’ than a lot of the other ARM boards which are less well developed in software terms. The huge numbers of Pis out there compared to pretty much every other SBC, and the massive number of developers, means you end up with a much better experience in lots of areas. I’ve got ODroid C1, C2, HC1 (and had a U2). I’ve got a Rock64. All… Read more »

I wonder why they don’t just do the migration is a seamless way, releasing a board with the compatible stuff and an alternate one with a new shiny SoC to start creating a solid base. After a couple of years it will have almost everything fixed and they will be able to cease releasing old ones. Simple and clean.
