You can install RoonBridge on any Rpi Linux distro. And you’re free to change Rpi Linux distro (as long as you use one which has kernel support for your Allo card). If Allo has run out of microSD cards with DietPi burned onto it, you can always burn one yourself.
@Jacques_Distler Thank you! So I’m clear, I can just burn Dietpi on any SD card say 16 gb or smaller? Is there anything in particular I need to have on it for the Allo hardware? Thanks again!
Allo pm’d me on Facebook and said that they have Rpi4’s with dietpi/web interface. Will that work as well/better? Are there any differences to be aware of?
