http://blog.armbian.com/content/images/2025/11/armbian_safe-operating.pngSingle Board Computers (SBCs) like the Raspberry Pi, Orange Pi, and Rockchip-based boards pack impressive computing power into compact designs but with that power comes heat. Keeping temperatures within a safe range is critical for performance, stability, and longevity. Most SBCs are designed to operate safely between 0°C and 80°C (32°F to 176°F), though the ideal range depends on the processor and workload. For example, ARM-based chips such as the RK3588 or Broadcom BCM2711 typically idle between 35°C and 50°C, and can safely run under sustained loads up to 70°C-75°C. Once the temperature reaches around 80°C-85°C, many boards begin to throttle, automatically lowering CPU frequency to prevent overheating. Prolonged operation near or above these limits can lead to degraded performance and, over time, shorten component life. To maintain safe temperatures: Provide airflow: Use open cases or add a small fan.Use heatsinks: Aluminum or copper heatsinks on the CPU dramatically reduce peak temps.Monitor regularly: Tools like sbc-bench, glances, or built-in thermal sensors help track heat trends.Avoid enclosed or sunlit areas when running high workloads.In general, keeping your SBC under 70°C during typical use ensures efficient operation and prevents thermal throttling. With proper cooling and monitoring, these small computers can run reliably for years even under heavy workloads. View the full article

Armbian, a leading Linux distribution tailored for single-board computers (SBCs), has officially announced the release of v25.8.1, a significant update that landed on August 2025. This release marks another stride in the project's mission to deliver a reliable, high-performance, and versatile Linux ecosystem for ARM-based devices. The latest version is a testament to the power of community-driven development, packing a wealth of improvements, expanded platform support, and robust kernel and bootloader updates that will benefit developers and enthusiasts alike. Kernels, Bootloaders, Firmware At the core of the August release is a strong focus on reinforcing the operating system’s foundation. The Armbian team has delivered extensive updates across both the Linux kernel and bootloader components. Most platforms have advanced to Kernel 6.16 on their EDGE branches, while the STABLE branch remains on the long-term supported Kernel 6.12. These upgrades go beyond new features bringing critical security patches, performance improvements, and broader hardware compatibility for Armbian users. In addition to kernel updates, this release also refreshes key firmware components. U-Boot and Arm Trusted Firmware (ATF) have been updated across multiple boards, enhancing the reliability of the boot process. These low-level improvements are essential to delivering a smooth and consistent user experience especially when supporting the wide variety of SBC hardware in the Armbian ecosystem. Board Support One of the most exciting aspects of any Armbian release is its growing hardware support and v25.8.1 is no exception. This release introduces new Platinum-supported boards, including the Mekotronics R58 HD and NanoPi R3S LTS, alongside several community-supported targets such as the CAINIAO CNIoT-CORE, KickPi K2B, Radxa Cubie A5E, Banana Pi R4, and Orange Pi 5 Pro. These additions highlight Armbian’s ability to keep pace with the fast-moving SBC market, while also reflecting the collaborative contributions of its community. Beyond new hardware, the release delivers important fixes and driver updates across existing platforms. Thermal sensors are now enabled on the Rock-5C, audio functionality has been restored on the RockPi-S, and the Wake-on-LAN service has been fixed on the Helios4. Driver support has been bolstered with new additions for the Realtek RTL8822CS and Innosilicon USB3 PHY, a touchscreen driver for the NanoPi M6 in mainline kernel, and key fixes for DSI displays on the Raspberry Pi 5. Together, these improvements strengthen Armbian’s position as a practical and versatile platform for everything from DIY smart home setups to demanding industrial applications. Userspace, Framework, armbian-config This release also brings a set of userspace, build framework, and configuration utility improvements. A key milestone is the official addition of Debian Trixie as a supported release, with this cycle focused on ensuring Trixie images are ready and stable. At the same time, a minimal Debian Bookworm image is kept for each target to maintain compatibility where needed. Other highlights include package adjustments on Trixie, correcting login screen alignment, updating the boot logo, and ensuring signing key management by keeping a symlink to the old location for compatibility. The build framework was also extended with support for the new loong64 architecture. The configuration framework (armbian-config) has also seen major updates. Networking features were expanded with improved WireGuard support, covering both client setups and LAN routing, while Pi-hole integration was improved with Unbound, and general bugfixes. Overlay management was made more reliable, and Docker installations became more robust. Continuous integration and testing were strengthened with better duplicate module detection and automated container cleanup, ensuring smoother development workflows. New functionality was added as well, including Cockpit support with KVM integration, and new modules such as Ghost CMS. Full changelogSee the full list of changes.

A common and effective way to use multiple kernels on a single-board computer (SBC) running Armbian is to use separate SD cards. This approach is especially useful for testing new kernels, experimenting with different kernel versions, or even trying out other Linux distributions all without risking your main, stable system. Since most SBCs prioritize booting from an SD card, this method keeps things simple and reliable. In this tutorial, we’ll walk through how to set up multiple SD cards with different Armbian kernels. PrerequisitesBefore getting started, make sure you have: Your SBC - e.g., Orange Pi, Rock Pi, Odroid, or another supported board.Multiple SD cards - one per kernel/system. Choose reliable, high-speed cards from a reputable brand to minimize boot problems.A computer to write images to the SD cards.A stable power supply for your SBC.Armbian images - downloaded for your board, each with the desired kernel (e.g., current, edge, or legacy). You can grab these from the official Armbian download page.Step 1: prepare the SD cards Each SD card will be flashed with a different Armbian image. Download imagesHead to the Armbian download page and find images for your SBC model. For example, download one with the current kernel and another with the edge kernel. Flash the SD cardsYou can use BalenaEtcher (GUI) or dd (CLI) to flash your cards. Using BalenaEtcher: Insert your SD card into the computer.Open Etcher, select the downloaded Armbian image.Select your SD card as the target.Click Flash!Repeat for each SD card and kernel image.Using dd (Linux/macOS): Unzip the .xz Armbian image file.Identify your SD card device name (lsblk or diskutil list). Example: /dev/sdX.Run: sudo dd if=/path/to/armbian-image.img of=/dev/sdX bs=1M status=progress && syncReplace /path/to/armbian-image.img and /dev/sdX with your actual image and device name. Be careful: choosing the wrong device can overwrite your computer’s storage. Step 2: initial boot and configuration Each flashed SD card is now a standalone system. Insert one card into your SBC and power it on.Armbian will run initial setup: resizing the filesystem and prompting you for a root password and new user.Once done, shut down the SBC safely.Swap to your next SD card and repeat the setup process.Every card remains completely independent, with its own configuration. Step 3: managing multiple kernels Now that you have multiple cards, you can swap between them as needed: Switching kernels: Power off the SBC, swap the SD card, and power it back on. The bootloader handles the rest.Testing and development: Keep a stable, “production” kernel on one card and experimental kernels on others. If something breaks, just pop the stable card back in.Isolation advantage: While armbian-config can switch kernels on one installation, using separate SD cards provides complete isolation. This prevents conflicts and makes troubleshooting far easier.Conclusion Running multiple kernels with Armbian doesn’t require advanced bootloader tweaks or complicated configuration. By simply preparing separate SD cards, you gain flexibility, reliability, and peace of mind while testing new kernels or exploring different setups on your SBC. View the full article
