Raspberry Pi Pico 2 W on sale now at $7

25 November 2024 at 14:59

Today, our epic autumn of product launches continues with Raspberry Pi Pico 2 W, the wireless-enabled variant of this summer’s Pico 2. Built around our brand new RP2350 microcontroller, featuring the tried and tested wireless modem from the original Pico W, and priced at just $7, it’s the perfect centrepiece for your connected Internet of Things projects.

RP2350: the connoisseur’s microcontroller, redux

When we launched our debut microcontroller, RP2040, way back in 2021, we couldn’t have imagined the incredible range of products that would be built around it, or the uses that the community would put them to. Combining a symmetric pair of fast integer cores; a large, banked, on-chip memory; rich support for high-level languages; and our patented programmable I/O (PIO) subsystem, it quickly became the go-to device for enthusiasts and professional engineers seeking high-performance, deterministic interfacing at a low price point.

RP2350 builds on this legacy, offering faster cores, more memory, floating point support, on-chip OTP, optimised power consumption, and a rich security model built around Arm’s TrustZone for Cortex-M. It debuted in August on Pico 2, on the DEF CON 32 badge (designed by our friends at Entropic Engineering, with firmware and a gonzo sidewalk badge presentation by the redoubtable Dmitry Grinberg), and on a wide variety of development boards and other products from our early-access partners.

Wireless things

Many of the projects and products that people build on top of our platforms β€” whether that’s our Linux-capable Raspberry Pi computers, our microcontroller boards, or our silicon products β€” answer to the general description β€œInternet of Things”. They combine local compute, storage, and interfacing to the real world with connectivity back to the cloud.

Raspberry Pi Pico 2 W brings all the power of RP2350 to these IoT projects. The on-board CYW43439 modem from our friends at Infineon provides 2.4GHz 802.11n wireless LAN and Bluetooth 5.2 connectivity, and is supported by C and MicroPython libraries. Enthusiasts benefit from the breadboard-friendly Pico form factor, while our upcoming RM2 radio module (already in use on Pimoroni’s Pico Plus 2 W) provides a route to scale for professional products which have been prototyped on the platform.

More to come

We’re very pleased with how Pico 2 W has turned out. And, where the Pico 1 series ended with Pico W, we have a few more ideas in mind for the Pico 2 series. Keep an eye out for more news in early 2025.

$7 Raspberry Pi Pico 2 W board launched with 2.4 GHz WiFi 4 and Bluetooth 5.2 wireless module

25 November 2024 at 14:59
Raspberry Pi Pico 2 W access point

As expected, the Raspberry Pi Pico 2 W – the wireless version of the Raspberry Pi Pico 2 – is now available with an extra 2.4GHz WiFi 4 and Bluetooth 5.2 wireless module at an official price of $7. We’ll go through the specs and perform a mini review in this post trying out both WiFi and Bluetooth code samples. It’s not the first Raspberry Pi RP2350 with WiFi and Bluetooth we’ve seen, as Pimoroni introduced the Pico Plus 2 W board with an RP2350B MCU and Raspberry Pi RM2 Wi-Fi and Bluetooth module, and iLabs launched the Challenger+ RP2350 WiFi6/BLE5 board relying on ESP32-C6 wireless module. However, the Raspberry Pi Pico 2 W is the official board, is cheaper, and will certainly be the most popular/widely used.

This Week in Beagle #6

25 November 2024 at 13:00

Hello everyone. Another light week here. Let’s go over everything.

BeagleY-AI SD Card support

While hacking on my BeagleY-AI, I found that my HP SD card did not work with BeagleY-AI for some reason. On digging a bit further, some SD cards were not working on BeagleY-AI due to some issues with signal voltage switching on the am62x platform. This has now been fixed, as seen in the following patch series. By switching out the Linux kernel to mainline, I was able to get the HP SD card to work. So, the SD card compatibility of BeagleY-AI will improve soon.

BeagleBoard Rust Imager

BeagleBoard Rust imager got lots of love this week.

AppimageLauncher Problem

As pointed out by Jason here, the BeagleBoard Rust imager appimage is not usable with AppimageLauncher. The issue seems to be that appimagetool uses ZSTD compression now, while AppimageLauncher does not support it yet. Moreover, it seems like AppimageLauncher makes the appimage unusable. For now, the recommendation is to either remove AppimageLauncher or at least deactivate it for the BeagleBoard Rust imager.

More information regarding the upstream issue can be found here.

SD Card Flashing Performance Improvements

While the SD card flashing worked, it was much slower than the original bb-imager. After some tinkering with the buffer size while flashing and using parallel decompression of xz images, SD card flashing should be much faster (flashing time decreases by 57%).

It is still a bit slower than the original bb-imager (about 1 min), but it seems related to the internals of QFile, so that would be much more work than just a day.

Debian Packages

BeagleBoard Rust imager now builds Debian packages in CI using cargo-deb. While the goal is to eventually have an upstream package using debcargo, there is not much point until bb-imager-rs hits v1.0.0. Additionally, since debcargo only seems to support building stuff already present in cartes.io, it does not seem suitable for experimental builds (although I could be wrong about that).

Experimental Builds

Builds from the latest main branch are now pushed to Package Registry rather than just being stored as build artifacts. This makes grabbing the latest development version of bb-imager-rs much simpler.

Note: Only the most recent build is kept around.

Ending Thoughts

This was it for this week. Hopefully, this helps bring transparency regarding where the development efforts are concentrated, and how the community can help. Look forward to next update.

Phoronix Premium Cyber Week Sale To Better Enjoy Our Linux Hardware Reviews & News

25 November 2024 at 12:00
While the end of year holidays are fast approaching, my commitment to Linux hardware and open-source software remains and there still is a lot of interesting content to come this year still -- each and every day, without change for roughly a decade. Unfortunately though due to the (sad) state of the ad industry, many major companies focusing on the likes of Facebook/Meta ads, and the frequent use of ad-blockers by Linux/FLOSS readers make ongoing operations increasingly difficult. But if you'd like to show some love this holiday season, the Phoronix Premium "Cyber Week" / "Black Friday" special is now taking place so you can enjoy the site ad-free, native dark mode support, multi-page articles on a single page, and other benefits while hopefully allowing the site to continue for years to come...

Mitigating a DoS attack with GoAccess and Cloudflare

24 November 2024 at 18:01
Cloudflare Under Attack Mode

In this off-topic post, I’m going to discuss some behind-the-scenes β€œfun” that may happen when managing the web server used to host the CNX Software website. From time to time, the server becomes unreachable, but I can still access its console, and notice a very high CPU load (over 100) on a VPS with four cores, while the CPU load is typically 0.5 to 2 under normal circumstances. That’s usually due to a DoS (denial of service), DDoS (distributed denial of service), or some bug I can’t identify. An easy way to solve this issue is to log in to Cloudflare and set the β€œUnder Attack Mode” to on. It will show all visitors a JavaScript challenge the first time they visit the website, and the CPU usage typically drops back to normal level within a minute or so. That means I can access my website and so do regular [...]
