RAKwireless open sources RUI3 multi-target IoT development platform

RAKwireless has made its RUI3 IoT software development platform open-source so that customers or users can implement “nice-to-have” features on top of the features already implemented by the company which could make it even more versatile in a wider range of IoT scenarios. Introduced in 2022, the RAK Unified Interface v3, or RUI3 for shorts, is a modular IoT platform based on the Arduino SDK with additional functions for IoT connectivity and low power that supports a variety of devices and applications. So developers can learn the language, code once, and use the same software on multiple WisBlock core platforms including Nordic Semi nRF52, STM32, ESP32, and Raspberry Pi RP2040 instead of having to juggle between different the Arduino BSP, the ESP-IDF framework, Nordic nRF Connect SDK, or Raspberry Pi C SDK. Users could already use the RUI3 firmware with the RAK3172 (STM32), RAK4630/RAK4631 (nRF52), or RAK11720 (Apollo3) WisBlock Core […]

Linux 6.8 release – Notable changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.8 on the Linux kernel mailing list: So it took a bit longer for the commit counts to come down this release than I tend to prefer, but a lot of that seemed to be about various selftest updates (networking in particular) rather than any actual real sign of problems. And the last two weeks have been pretty quiet, so I feel there’s no real reason to delay 6.8. We always have some straggling work, and we’ll end up having some of it pushed to stable rather than hold up the new code. Nothing worrisome enough to keep the regular release schedule from happening. As usual, the shortlog below is just for the last week since rc7, the overall changes in 6.8 are obviously much much bigger. This is not the historically big release that 6.7 was – we seem to […]

MINIX Z100-0dB review – Part 3: A fanless Intel N100 mini PC tested with Ubuntu 22.04

After the first part of the review with an unboxing and a teardown of the MINIX NEO Z100-0dB mini PC, we tested the fanless Intel N100 mini PC with Windows 11 Pro in the second part, and we are now ready to report our experience with Linux, and more specifically Ubuntu 22.04, on the MINIX Z100-0dB mini PC in the final and third part of the review. We will go through features testing, run some benchmarks to evaluate the performance in Linux, perform storage and network performance tests, check the cooling ability of the mini with a stress test, and also check its power consumption under different scenarios. We will also compare the MINIX Z100-0dB to the actively cooled GEEKOM Mini Air12 mini PC that uses the same Intel Processor N100 CPU. Ubuntu 22.04 installation We will install Ubuntu 22.04 alongside Windows 11 Pro in dual boot configuration, so we […]

AMD announces the Spartan UltraScale+ FPGA family for cost-sensitive and IO-intensive applications

The Spartan UltraScale+ FPGA family is the latest inclusion to AMD’s Cost-Optimized portfolio, a series of FPGAs designed to balance cost, power, and form factor with affordability. The UltraScale+ FPGA family is designed for cost-sensitive, low-power applications requiring high I/O count and substantial security. Devices in the Spartan UltraScale+ family offer a high I/O to logic cell ratio for FPGAs built in 28nm and lower process technology (the highest in the industry, according to AMD), consume up to 30% less power than compared to the previous generation, and feature robust security features that outclass the rest of the Cost-Optimized portfolio. This FPGA family is built on the same UltraScale+ architecture as previous Artix and Zynq products. They are the first AMD UltraScale+ FPGAs to feature a hardened DDR memory controller and PCIe Gen4 x8 support, “providing both power efficiency and future-ready capabilities for customers.” AMD Spartan UltraScale+ specifications: System Logic […]
