Armbian 21.08 for Arm boards ships with latest Linux 5.10 LTS

Armbian provides stable releases four times a year, and Armbian 21.08 has just been released offering minimal, server or XFCE, Cinnamon and Budgie desktop Linux 5.10 LTS images for Arm boards, as well as a build system to customize your own image. If you’ve been using an Arm SBC that is NOT a Raspberry Pi board, you’ve probably been told to use Armbian, as the community is providing Debian and Ubuntu images for over 100 Arm boards that are either “Supported”, “WIP” (suitable for testing), or “CSC” (no official support, aka you’re on your own). Armbian 21.08 highlights (Note: EDGE are daily builds following daily builds of the Linux kernel and fresh packages from Debian sid, Ubuntu 21.04 “hirsute” or Ubuntu 21.10 “impish” userland): Based on Linux 5.10.59 released on August 15, 2021 Minimal, server or XFCE, Cinnamon, and Budgie desktop Fast automated language selection on the first run Regular […]

LibreELEC 10.0 minimal Linux OS for media playback released with Kodi 19.1

While most TV boxes and SBCs nowadays ship with or support a version of Android, people who just want the best viewing experience may prefer to switch to a Linux distribution such as LibreELEC or CoreELEC. The good news is that LibreELEC 10.0 has just been released with Kodi 19.1 and Linux 5.10 LTS. LibreELEC 10.0 is said to work well for Allwinner, Rockchip, and “Generic” Intel/AMD devices, while the Raspberry Pi 4 release’s codebase is rather new, and there may still be a few rough edges. Support for the previous generation Raspberry Pi boards has been dropped, and there’s no support for Amlogic platforms as CoreELEC already provides good support. Since LibreELEC 10.0 is based on Kodi 19.1, it benefits from the same features as Kodi 19 “Matrix” release including AV1 video decoding, a new skin, HDR support, and more. LibreELEC 10.1 support a wide range of single board […]

Top 5 most powerful Arm SBC’s & Devkits in 2021

Most Powerful Arm SBCs development kit 2021

While companies like Hardkernel, Raspberry Pi, Orange Pi, and FriendlyArm offers affordable, great little Arm Linux development boards that are suitable for many projects, in some cases, your requirements may lead you to spend a bit more for either extra CPU power, more memory, AI processing power, faster I/Os and so on. That’s why I did a list of the most powerful Arm single board computers in late 2017, but with over three years passed since then an update is warranted. The boards from the list must be easily purchasable from individuals (with the cash to spare) or small companies, so we’ll exclude hard-to-source hardware, as well as Arm server boards like Ampere eMAG motherboard, that do not really qualify as single board computers. Snapdragon 888 Mobile Hardware Development Kit While there are plenty of Cortex-A72/A73 development boards around, it’s much hardware to find one with more recent Cortex-X1 or […]
