Open Hardware: Arduino IDE, Raspberry Pi Pico/CM4, and More

Announcing the Arduino IDE 2.0 (beta)
The Arduino IDE is the well-known software we all use to program our boards. Its development started in 2005 based on the graphical interface of the Processing project and has never stopped since. During these years, countless hours of development by the Arduino team with the help of a vibrant community made the Arduino IDE the de facto standard for electronics prototyping. Thanks to an extensible framework based on modular board support packages, the IDE supports more than 1,000 official and non-official boards; it’s translated in 66 languages, mentioned by more than 3,000 books, and is still growing: during the last year, it was downloaded more than 39 millions of times. More than ever.

A neat way to add a reset button to Raspberry Pi Pico
The Raspberry Pi Pico is a nice little board, but if you program in C language, you’d need to disconnect the micro USB cable each time you’d like to flash the UF2 firmware. That’s not convenient and could damage your board over time. The Raspberry Pi Foundation even decided to write a blog post explaining how to add a reset button to your Raspberry Pi Pico using a breadboard circuit.

Raspberry Pi CM4 Carrier Board comes with RS485/Modbus, CAN, 1-wire interfaces (Crowdfunding)
Another day, another Raspberry Pi CM4 carrier board. Just like the TOFU carrier board, CM Hunter carrier board for Raspberry Pi CM4 targets industrial applications, but in a different way, as it focuses on industrial communication protocols with Galvanically-Isolated RS485/Modbus, 1-Wire, CAN 2.0B, and together with more common interfaces like Ethernet, HDMI, USB, etc…
[...]
The project will be open-source hardware with Eagle Schematic and PCB design files, custom libraries, BOM, part numbers, and custom Raspbian Image with all Python libraries and instructions released once the crowdfunding campaign is over.
The Raspbian (Raspberry Pi OS) image comes with the FBCP driver for the display, and a demo user interface based on Python 3.7, PySide2 5.12, and QML 5.12 to showcase and control the Modbus, CAN, 1-Wire interfaces respectively using python-can, modbus_tk, and Pyownet open-source libraries, as well as the RTC and the relay.

3.5-inch Atom x6000E embedded SBC features 3x GbE, 2x SATA, 6x USB, and more
Several Elkhart Lake SBC’s integrate two Ethernet ports including Avalue ECM-EHL 3.5-inch SBC or Congatec Conga-PA7 Pico-ITX board with the former equipped with 2.5GbE and GbE ports, and the latter two GbE ports.
But if your industrial project requires more Ethernet ports, iBase IB836 3.5-inch Atom x6000E embedded SBC offers three Gigabit Ethernet RJ45 ports, as well as two SATA ports, six USB interfaces, plus various display options, as well as M.2 and mPCIe expansion sockets.

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. |
