Ubuntu Core 26 targets IoT devices and embedded systems, offers up to 15 years of security maintenance

Ubuntu Core 26

Canonical has just introduced Ubuntu Core 26, based on the recently-released Ubuntu 26.04 LTS and designed for IoT devices and embedded systems, with precise Linux builds, optimized OTA updates, live kernel patching, and enhanced hardware-backed protection for mission-critical deployments. Offered with up to 15 years of security maintenance, Ubuntu Core 26 minimal, immutable operating system enables reduced installation times, 90% smaller OTA updates, and precision-led builds via Chisel. Every component is a containerized snap, just like in prior Ubuntu Core releases. Canonical says it can help companies meet requirements for the EU Cyber Resilience Act (CRA) with securely designed and private AI deployments relying on hardware-based trust. Ubuntu Core 26 highlights: Faster snap installation and updates – An improved snap-delta format reduces update sizes between 50% and 90% for most snaps. For instance, updates to the Core base snaps dropped from 16MB to 1.5MB in size. This lowers data usage […]

Up to 256 MB FERRIT modular F-RAM storage device preserves critical data for up to 200 years

FERRIT F-RAM storage

Machdyne’s FERRIT is a modular USB F-RAM storage device with a capacity of up to 256 MB and capable of storing data for up to 200 years with a virtually unlimited number of writes and high-radiation resistance. It builds upon the earlier Blaustahl F-RAM storage device that only offers 8KB capacity. The FERRIT device supports 8 MB to 256 MB by combining up to 256 individual 1 MB F-RAM ICs. The prototype below is housed in a metal frame and looks like a typical cluster solution. FERRIT specifications and key features: FERRIT-CY controller based on Raspberry Pi RP2040 MCU with USB-FS Type-C port FERRIT-M8 removable ferroelectric memory cards with up to 16MB capacity using 16x 1MB F-RAM ICs (double-sided: 2x 8 chips) FERRIT-16 backplane with slots for FERRIT-CY and 16x FERRIT-M8 connected over SPI/QSPI bus Max capacity – 256 MB+ through up to 256x memory devices (16 memory cards with 16 chips) […]

Pi Slate – A Raspberry Pi 5 handheld Linux cyberdeck with a 5-inch 1280×720 touchscreen display

Pi Slate

We previously wrote about Carbon’s CyberT, a Blackberry-style Raspberry Pi CM4 handheld Linux cyberdeck designed for Kali Linux and penetration testing. The company, now operating under the CyberArch/Carbon Computers brand, has introduced the Pi Slate, a more powerful handheld cyberdeck designed for portable computing and security-focused applications. Built around the Raspberry Pi 5, the Pi Slate integrates a 5-inch 1280×720 touchscreen, a backlit RGB keyboard with an integrated cursor, and a 10,000 mAh battery for 3–5 hours of portable use in a compact enclosure. It supports modular expansion for HATs such as LoRa, SDR, AI accelerators, and M.2 storage, and includes cooling support, antenna mounts, and an optional modular back with a kickstand. It targets penetration testers, IT professionals, and field technicians needing a compact, preconfigured system for cybersecurity and field work. Pi Slate specifications: SBC – Raspberry Pi 5 with 2GB, 4GB, 8GB, or 16GB LPDDR4X RAM options Storage […]

6.67-inch flexible AMOLED display works with Raspberry Pi, LattePanda, and other SBCs with HDMI output

6.67-inch flexible display

DFRobot has introduced a 6.67-inch flexible AMOLED display with a 2400×1080 resolution, designed for easy use with single-board computers such as Raspberry Pi and LattePanda. While flexible displays are common in smartphones, they are difficult to interface with SBCs, so DFRobot added a dedicated MIPI-to-HDMI driver board for plug-and-play compatibility with a wider range of platforms. The panel is just 1.2mm thick and bendable, enabling curved and space-constrained designs, while delivering 450 cd/m² brightness and 16.7 million colors. Like typical OLEDs, it offers deep blacks and high contrast without requiring a backlight, making it suitable for applications ranging from wearables and robotics to industrial HMI systems. DFRobot 6.67” flexible AMOLED Display specifications: Compatibility – Raspberry Pi, Banana Pi, Orange Pi, and most devices with an HDMI output. Display Panel Screen Size – 6.67 inches Screen Material – Flexible AMOLED Resolution – 2400 x 1080 (SPR – Sub-Pixel Rendering) Aspect Ratio […]
