Linux 6.19 Release – Main changes, Arm, RISC-V, and MIPS architectures
Linus Torvalds has just released Linux 6.19 on the Linux Kernel Mailing List (LKML): No big surprises anywhere last week, so 6.19 is out as expected – just as the US prepares to come to a complete standstill later today watching the latest batch of televised commercials. The betting man would expect them all to be AI-generated, but maybe some enterprising company decides to buck the trend? Doubtful, but there’s always a slight chance. But for anybody outside the US, maybe taking the newest kernel out for a spin instead is an option? I have more than three dozen pull requests for when the merge window opens tomorrow – thank you to all the early maintainers. And as people have mostly figured out, I’m getting to the point where I’m being confused by large numbers (almost running out of fingers and toes again), so the next kernel is going to […]
Olimex HoT aims to be lightweight, easier-to-use alternative to Home Assistant
Olimex HoT (Home of Things) is a lightweight Smart Home solution designed to run on low-end hardware (128MB RAM, 128MB flash) and interface with nodes running ESPHome. It can serve as an easier-to-use alternative for people who don’t need all the bells and whistles provided by powerful home automation frameworks such as Home Assistant or OpenHAB. Home Assistant open-source home automation software is great, but it requires a system with at least 2GB of RAM, and 4GB of RAM is often recommended for most users. There’s also a steep learning curve. This is what Tsvetan Usunov, Olimex CEO, realized last year when he tried Home Assistant, and he decided to start working on a low-cost, easy-to-use solution for IoT and Smart Home applications. That’s why the Olimex HoT project was created. Tsvetan gave a talk about the project entitled “Designing EUR 20 Open Source Hardware running Free/Libre Open Source Software […]
Forlinx OK153-S12 Mini – A low-cost Allwinner T153 SBC with Raspberry Pi GPIO header and long-term availability
Forlinx has introduced the OK153-S12 Mini, an Allwinner T153 SBC/development board, which looks to be a low-cost version of the OK153-S SBC that we previously covered. It keeps the same FET153-S SoM, but swaps the industrial terminal blocks, mini PCIe, and some other interfaces for a more compact footprint and a Raspberry Pi-compatible 40-pin header. The SBC supports up to 1 GB of DDR3 memory, up to 512 MB of NAND flash or 8 GB eMMC flash, and also features a microSD card slot for storage. Other interfaces include two Gigabit Ethernet ports, two USB Type-C ports for power, data, and debugging, and a USB 2.0 host port. Display is supported via an RGB LCD interface with backlight control via PWM. Other features include mono audio line-out via a 3.5mm headphone jack, multiple GPIOs, and buttons for reset, download, and user input, along with various status LEDs, and a 40-pin […]
NetCube Systems Nagami Allwinner T113-S3 mini PCIe SoM features ESP32 wireless SoC, supports mainline Linux
NetCube Systems Nagami is a small Allwinner T113-S3 system-on-module that I just saw added to Linux 6.18. Besides mainline Linux support, the Allwinner SoM offers somewhat unique or unusual features that include a mini PCIe form factor and an ESP32 co-processor for WiFi 4 and Bluetooth connectivity. The Nagami also comes with 128MB DDR3 embedded in the T113-S3, 4GB eMMC flash, a Fast Ethernet PHY, and a Qwiic connector for I2C expansion modules. All I/Os are exposed through a standard mini PCIe edge connector: audio I/Os, Ethernet, USB 2.0 OTG/host, and a range of low-speed I/Os. Nagami SoM specifications: SoC – Allwinner T113-S3 CPU – Dual-core Arm Cortex-A7 @ 1.2 GHz with 32 KB L1 I-cache + 32 KB L1 D-cache per core, and 256 KB L2 cache DSP – Single-core HiFi4 VPU – H.265/H.264 video decoding up to 1080p60 and JPEG/MJPEG video encoding up to 1080p60 Memory – 128 […]
Linux 6.18 LTS release – Main changes, Arm, RISC-V, and MIPS architectures
Linus Torvalds has just announced the release of Linux 6.18 on the Linux Kernel Mailing List (LKML), which will likely become the next LTS kernel [update: it’s now official]: So I’ll have to admit that I’d have been happier with slightly less bugfixing noise in this last week of the release, but while there’s a few more fixes than I would hope for, there was nothing that made me feel like this needs more time to cook. So 6.18 is tagged and pushed out. Most of the last-minute fixes are minor fixes to drivers, with some random noise elsewhere (bluetooth, ceph, afs..). Nothing strikes me as standing out, but hey, there’s a shortlog appended if you want to see the details. And this obviously means that the merge window will open tomorrow, and I already have three dozen pull requests pending. Thanks. And as I already mentioned a couple of […]
Black Friday and Cyber Monday 2025 – International deals, coupons, and events
Like every year since 2014, I’ll list a few international deals for Black Friday and Cyber Monday 2025, as many CNX Software readers cannot benefit from promotions on Amazon’s Black Friday and Cyber Monday events, which will take place from November 20 to December 1. I’ve gathered various deals, discount coupon codes, and events from relevant manufacturers of single board computers, MCU development boards, mini PCs, Smart Home devices, and DIY products, as well as popular online stores, including AliExpress, Banggood, and others. AliExpress Black Friday and Cyber Monday 2025 event AliExpress sales event for Black Friday and Cyber Monday 2025 has just started and will last until December 3, 2025 (although I can see until November 29 and December 4 in some places). You can use some of the coupons on the screenshot above, or some alternative coupon codes for the US and some other countries (excluding DE, RU, […]
Waveshare MK20 macro keyboard features twenty mechanical keys with 0.85-inch color LCD keycaps
Waveshare MK20 is a multifunctional macro keyboard with twenty mechanical keys featuring 0.85-inch LCD keycaps. As an upgrade to the earlier MK10 model, it adds a 2.8-inch secondary display along with two control knobs. The device supports AI voice interaction, real-time data display, and smart home integration with Home Assistant. Like its predecessor, the MK20 relies on a dual-system architecture: an Allwinner T113-S3 dual-core Cortex-A7 processor runs Linux to drive the displays, and a GD32 microcontroller runs QMK for low-latency keyboard and knob input. Each LCD key offers 128×128 resolution and supports dynamic images, videos, and multi-layer overlays, while the 2.8-inch secondary display (428 × 142 resolution) provides status or customization information. The keyboard also includes two rotary encoders with aluminum caps for volume, playback, or timeline control. The device is built with an aluminum alloy top case and a 2.5D acrylic lens for durability. Waveshare MK20 specifications: Main Controller – Allwinner […]
