Hardware With Linux: Raspberry Pi, Arduino, Nordic Semiconductor, Gigatron and LibreRouter
-
Ever evolving
A recent core movement has been greatly helped by the Raspberry Pi Foundation. Makers around the globe had been tinkering more and more with open hardware – with the Arduino for one – as the price and complexity fell. The Raspberry Pi was the icing on the home-made cake, with all the abundant resources the Foundation brought with it. This issue we’re celebrating maker culture and helping all the many people that we expect will be wondering what to do with their new toys after Christmas. So jump on board and join the maker revolution and build something fun, something shared and something open source!

Customizable, Atom-based DIN-rail PC supports Linux
Lanner’s “LEC-3034” is a fanless, Intel Bay Trail based DIN-rail box PC with up to 4x GbE, 4x USB, and 8x isolated serial ports plus SATA and mSATA storage and M.2 support for 4G.
Lanner’s line of industrial computers, which includes its recent, Apollo Lake based NVA-3000 embedded vision computer, now has a new DIN-rail mountable PC that harkens back to Intel’s previous Bay Trail generation of Atom SoCs. The fanless, 169.5 x 127 x 69mm LEC-3034 runs Linux 2.6 or Windows 7 on a dual-core, 1.33GHz Atom E3825 and supports -40 to 70°C temperatures.

Nordic Thingy:52 Dev Kit (First impression)
Today I'm playing around with a Nordic Thingy:52 Bluetooth 5 development kit from Nordic Semiconductor.

Gigatron – some assembly required
I don’t know if 74 chips have got smaller since I was a kid or if I’ve just got bigger but this is a test of dexterity.

Gigatron – chips are down

The LibreRouter project aims to make mesh networks simple and affordable
In the city, we’re constantly saturated with the radio waves from 10 or 20 different routers, cell towers and other wireless infrastructure. But in rural communities there might only be one internet connection for a whole village. LibreRouter is a hardware and software project that looks to let those communities build their own modern, robust mesh networks to make the most of their limited connectivity.
The intended use case is in situations where, say, a satellite or wired connection terminates at one point, the center of an area, but the people who need to use it live nearby — but well outside the hundred feet or so you can expect a Wi-Fi signal to travel. Often in such a case it’s also prohibitively expensive to run more wires or install cellular infrastructure.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
