The Raspberry Pi Foundation unveils the Raspberry Pi 4 – TechCrunch

Published

on

The Raspberry Pi 4 is here — and it’s an awesome upgrade. Earlier rumors said that it would take a while before a major Raspberry Pi upgrade, but it’s available starting today.

When it comes to physical design, the Raspberry Pi 4 Model B looks a lot like the Raspberry Pi 3 Model B+, the previous flagship model. It’s a single-board computer with a lot of connectors that is the size of a deck of cards.

But everything has been updated. It starts with a faster system-on-a-chip. The processor now uses the Cortex-A72 architecture (quad-core 64-bit ARMv8 at 1.5GHz). It supports H.265 hardware video decoding for instance.

The Raspberry Pi has been stuck at 512MB or 1GB of RAM for years. For the first time, you can buy models with more memory if you want more memory. The base model still starts with 1GB of RAM. But you can optionally buy a model with 2GB RAM or even 4GB of RAM.

In addition to raw memory capacity, memory transfer speeds should be faster as the foundation is switching from LPDDR2 to LPDDR4.

The Raspberry Pi Foundation has already sent me a Raspberry Pi 4 and I plan to run some benchmarks and share the results. I’m just waiting for the Raspbian update as the existing release doesn’t run on the new architecture — I realized that after formatting the microSD card to replace the pre-installed NOOBS operating system with Raspbian Lite (oopsie).

When it come to connectivity, the two big changes are that you now get true Gigabit Ethernet (instead of Ethernet over USB 2.0). It should open up a ton of potential use cases for servers and headless Raspberry Pi devices.

There are now two USB 3.0 ports and two USB 2.0 ports. And you now get a USB-C port for the power brick. Bluetooth is also getting an update from Bluetooth 4.2 to Bluetooth 5.0.

The final big hardware change is that the full-size HDMI port is gone. You now get two micro-HDMI ports, which let you plug two 4K displays at 60 frames per second using one Raspberry Pi. I haven’t tested that setup yet. I’m sure it would be fine to run two statics dashboards in your office for instance, but I wouldn’t expect crazy dual-screen performances.

The rest of the specifications should look familiar to anybody who has used a Raspberry Pi in the past. There’s a microSD card slot so that you can put the operating system and user data on a memory card. There’s a 40-pin GPIO header that should be compatible with existing add-on boards.

The product is launching today through authorized Raspberry Pi retailers. The base model still costs $35, while the 2GB RAM model costs $45 and the 4GB RAM model costs $55.

While the Raspberry Pi first started as a simple computer designed to teach kids how to code, it has become a versatile device with many different use cases. I’ve been using a few for the past couple of years and I learned a lot about programming, system administration, Docker containers and networking. And it looks like today’s update will be a hit for kids, parents and makers.

Report: Windows 11 22H2 update will be released on September 20

Windows 11’s first major update, also called Windows 11 22H2, is due to be released to the public on September 20, according to separate reports from The Verge and Windows Central.

The update has been available in near-final form in Microsoft’s Windows Insider Preview channels since May, and we’ve already covered most of its major changes—Windows 11 22H2 will include a few new security features (and new default settings for existing features), a redesigned Task Manager, new touchscreen gestures and window management features, and tweaks for the Start menu and taskbar, among other things. It also continues to replace old bits of Windows 8- and 10-era UI (like the brightness and volume indicators) with rounded Windows 11-style versions, bringing more visual consistency to Windows PCs.

Like all major Windows updates, it likely won’t be offered to all current Windows 11 users on September 20. Microsoft usually sends the update to a small number of PCs first and gradually expands availability until all Windows 11 PCs have installed it. Users can manually install new updates by downloading an ISO or using the Windows 11 Installation Assistant from this page.

Microsoft’s update plans for Windows have changed a lot in the last year, and they’re reportedly still in a state of flux. The company said last year that Windows 11 would receive major updates once a year and that Windows 10 would move from its twice-a-year update model to the same once-per-year schedule. But even as the pace of major updates has officially slowed down, Microsoft has also made some changes to its development and release practices that allow it to roll out small- to medium-size changes at shorter intervals. In the 10 months since Windows 11 was released, we’ve gotten a long list of user interface tweaks, updates for a number of preinstalled first-party apps, and Android app support. Microsoft also reportedly plans to go back to releasing new numbered Windows versions every three years or so, although the company has neither confirmed nor denied this.

For Windows 10 users who can’t or don’t want to install Windows 11, Windows 10 is getting its own 22H2 update. Microsoft released a preview build for it late last month, but the company isn’t talking about what this update actually does. It’s not likely to include many big user-facing improvements.

Pixel 6 owners who upgrade to Android 13 can never go back

Published

on

Android 13 is slowly rolling out to Pixel phones, but here’s something to consider when that update message finally pops up on your device: You can never go back.

Google is apparently changing the way Android updates are enforced on its latest devices. A new warning message on the Pixel Factory Image page says that the Pixel 6, 6 Pro, and 6a can never go back to older versions of Android once they update:

Anti-rollback was first introduced in Android 8 as a security feature. Google can patch all the exploits it wants, but security fixes are meaningless if an attacker can just roll back a device to a previous version that’s full of security holes. Rollback protection works by recording the newest installed version into tamper-evident storage that persists across device wipes, and now the system knows if it’s on an old version or not. Previously, this feature would just show a warning message on boot (and it looks like that will still happen on the Pixel 5 and lower), but now, Google plainly says of the Pixel 6, “You will not be able to flash older Android 12 builds.”

It’s not clear why only the Pixel 6 is affected by this change. If you don’t count Android 12L, this is the Pixel 6’s first major OS update. The three phones listed are also the only three phones that use Google’s first in-house SoC, the Google Tensor, so maybe the chip is flexing its muscles with new anti-downgrade capabilities.

This isn’t a big deal for most consumers, but in previous Android versions, it was nice to have an escape hatch if Google came out with a particularly buggy first release. If you frequently try out different software builds, this change will presumably mean that you can’t use any older third-party ROMs, either.

Almost-certain Nest Wifi appears at FCC with Wi-Fi 6E on-board

Published

Google has a new device awaiting approval at the FCC, and all signs point to it being an updated Nest Wifi router that not only addresses the notable lack of Wi-Fi 6 on its last model but leapfrogs ahead to Wi-Fi 6E.

In FCC documents made available yesterday, Google asked the FCC to keep confidential its schematics and operational details, including an “Internal Proprietary Antenna Solution consisting of 6 antennas.” As pointed out by Android Police, the fillings also show support for the 6 GHz frequencies of Wi-Fi 6E. There are also the standard 2.4 and 5 GHz bands, Bluetooth Low-Energy, and the 2.4 GHz frequencies that smart home connection standard Thread relies upon.

The model number—A4R-G6ZUC—is akin to other Nest products, and 9to5Google says it has confirmed that this is the number for the next Nest Wifi router.

In late 2019, when Google skipped Wi-Fi 6 for Nest Wifi, citing (questionable) cost concerns, we noted that a Wi-Fi 6 router wouldn’t do much for a home mostly filled with Wi-Fi 5 and 4 (i.e., 802.11ac and 802.11n) devices. And yet, had Nest’s router and points used Wi-Fi 6, their ability to use this newly freed-up spectrum space to speak to newer devices—and especially for backhaul moving of traffic from node to node—could have benefitted homes full of noisy devices or those competing with close-by neighbors’ gear.

It’s the same story with Wi-Fi 6E. There’s a small list of devices using the relatively recent Wi-Fi 6E right now: the Pixel 6 and 6a, Samsung’s Galaxy S21 Ultra, some brand-new laptops (not including the latest MacBook Air), and any PC you upgrade yourself with a 6E card. Wi-Fi 6E also lets devices make use of the wider 80 and 160 MHz channels, opening up capacity and reducing interference.

It’s worth noting that this FCC filing is only for a Nest Wifi router. It remains to be seen whether Google will offer Nest hubs with built-in speakers, as with the previous Nest Wifi. One more notable improvement Google could latch onto new Nest hubs would be Ethernet ports, something painfully lacking from the current generation.

In our benchmark review of Nest Wifi, we were impressed with Nest’s coverage of a 3,500-square-foot, difficult-layout home but found lots of room for improvement. Given the other options available at the same price points, it seemed like an option best suited for those already enthusiastic about Google Assistant speakers.

By the time Nest Wifi arrives (likely at an October Google hardware event), there will probably be strong Wi-Fi 6E mesh competition. We’ll see if the product has the same value proposition then.
