        OpenRex boards arrived and booted up to Linux GUI! In the coming weeks we will release the complete Altium
        project for everyone. <br><br>

        This is our biggest and the most complex open source project. We not only plan to create the HW, but we plan to
        do a lot of software and documentation around it. I hope, you will helps us as we really do need help with
        software!
