Yeah – just looking at it I can’t imagine it’s a clean signal by any stretch (and I doubt this was a factor in the design). I definitely don’t feel like spending ~$60 just to hook it up to a scope and see what it’s doing.
I did find some much higher quality pics from their press kit (if Discourse munges them, click to get high res version). It looks like the most of the part numbers are deliberately obscured but you can clearly see many of the traces.
