The developers of elementaryOS have announced their experimental construction for ARM chips of the Raspberry Pi 4 series. In other words, the support of this famous distribution based on Ubuntu, and with a very "mac" air, is approaching the SBC board. Therefore, if you already use elementaryOS on your PC, you should know that you can also do it on these boards.
This is not the first time that the elementaryOS project has entered the realms of ARM. They already released their operating system for ARM-based chips in August this year, so that it could work with the Pinebook Pro. Now, its latest version, elementary OS 5.1 "Hera" is getting experimental support for the Raspberry Pi 4.
Linux has been around for a long time running on ARM, and there are many distributions that do it specifically on the Raspberry Pi, as you already know. But now this other joins, for fans of Pantheon.
Really it is not a novelty, You already know that for several years, the main distributions (Arch, openSUSE, Ubuntu, Debian,…) have been present on Raspberry Pi boards. But that changed after the release of the Raspberry Pi 4, although the new technical specifications of this SBC make it even easier to run these distros.
Now, little by little, the distros that already had support for other SBC, They are also coming to the Pi 4, as is the case with elementaryOS, or Ubuntu, which a while ago also launched its official 20.10 image for the Raspberry Pi 4.
If you are interested in testing elementaryOS on your Raspberry Pi 4 and don't want to wait, you should know that its developers they have published a build under your program Early Access Builds. So you can already try the experience if you want to be one of the sponsors of the elementaryOS project. Although you can also Download this build by following the instructions you can find on this repository site GitHub.
Of course, keep in mind that this is a experimental launch, so do not expect wonders. Many things work correctly, but maybe some functions do not, or have some problems. For example, there are some graphical problems that need to be improved, as well as some glitches with the sound system ...
