Sprout Pi Mainboard – A modern, RP2350-powered motherboard for iPods

This is so cool. I've got a couple of iPod Classics in a drawer - alas it doesn't seem to work for them (presumably the colour display adds complexity?). I was wondering if this was possible last time I fished out my iPod - mostly the extra complexity of modern music streaming isn't needed, but bluetooth headphones and casting are great.
