Well this is quite interesting. Framework Computer, the company that builds the fab modular Framework Laptop has announced the release of the Framework Laptop Mainboard.
This is available for USA and Canada with a release upcoming for the UK, Germany, France, Netherlands, Austria, and Ireland sometime "soon". What's really fun though, is that they say it was designed in a way that you can simply use the mainboard as a standalone single-board computing platform. As they say "All you need to do is insert memory, plug in a USB-C power adapter, and hit the tiny power button on-board, and you’ve got a powered-up computer".
They also released the CAD files and electrical documentation under Creative Commons licensing, to encourage people to do whatever they want with it and they also released two 3D printable reference designs to go with it. Going even further, they're opening up a developer program to give away 100 i5-1135G7 Mainboards.
Additionally, they're trying to improve the Linux situation for their hardware too. While it already works quite well, they're going above and beyond what most other traditional vendors do. They've launched a dedicated Linux page, to show off how it works across different distributions and to give more info.
Really liking what they're doing.
