I would try it with the free Astroberry first. To know it would not harm the Pro would be assuring. Having a Pi with 12v ports would be a Plus instead of investing in another Pi. You see I have the ASIAir Plus already and want to find the Pro useful in another way. So Laurent you can go back to the Pro original use after using it as a Stellarmate OS? Either company will not confirm it, they just say they don't support it of course.
