We’ve added a powerful new Image Flashing Tool to Armbian! You can now browse, download, and flash Armbian images directly to your device’s internal storage or boot media - no external tools required. Everything happens seamlessly inside armbian-config, making installation and re-installation faster, safer, and easier than ever.

Key features

Module pulls data from the official download infrastructure JSON stream and uses simple and robust components to provide a seamless "search & flash" experience.

1. Interactive image browser

Finding the right image is now significantly easier. Forget about slow web browsing. The tool includes a robust filtering system that allows users to select images based on:

Kernel branch: choose between different kernel branches (legacy, current, edge).
Image variant: select specific desktop environments, server or minimal builds.
Stability: a specific "stability" filter allows users to toggle production-ready or daily builds.
Preinstalled applications: filter for specific software stacks.

UX enhancements:

Promoted builds: recommended images are highlighted with a star (★).
File size: image sizes are clearly displayed in MB.

2. Enhanced Safety Measures

Flashing operating systems always carries a risk of data loss if the wrong drive is selected. This update introduces critical safety checks:

System drive protection: The tool automatically hides any disk that contains active system partitions (e.g., /, /boot, or /boot/efi).

3. Improved Download Experience

The download and flash process has been polished to deliver clearer progress information and a smoother workflow.

Automatic fast mirror selection: The tool intelligently selects the fastest available Armbian download mirror to ensure optimal throughput and minimal latency.
Accurate progress bars: Leveraging pv (Pipe Viewer), the flashing workflow provides precise, real-time progress indicators for both download and write operations.
Graceful fallback: If pv is not available on the system, the tool automatically falls back to curl’s native progress meter, preserving usability without compromising reliability.

How to use?

New functionality has been added to armbian-config and armbian-install CLI tools.

Armbian weekly newsletter

This week, we spotlight the latest progress surrounding the Armbian 25.11 release. Development continues at a steady pace, with new board enablement work, kernel refinements, and package updates rolling in from contributors across the community. From single-board computers powering homelabs to lightweight systems deployed at the edge, Armbian 25.

How to test a USB-C power supply when your SBC has power issues

Power problems are one of the most common causes of instability, boot failures, or random restarts in single board computers (SBCs). Because many modern boards use USB-C connectors for power, it’s important to verify that your power supply is delivering the correct voltage and current before assuming there’s

Thermal paste vs. Thermal pads

Thermal pads are convenient, but thermal paste can drop your SBC's temperature by 5-8°C under load. Learn why switching to paste creates better heat transfer and prevents throttling, especially during intensive tasks.

v25.11 Improving the base, unlocking new options

Thanks to our amazing community and partners, this release brings mainline U-Boot support to more boards, adds dozens of new devices, and introduces powerful build framework improvements.
