I agree with you, Seth, about RN52 antenna's position : I never had any issue with its original position and I think it was a wise choice to avoid any damage to it or the whole chip ;)

Having time, I improved my previous layout to keep + and - lines of balanced audio signals the closest possible along their path by routing one signal on each side of PCB, as it appears to be a strong recommandation for balanced audio signals.
I used round angles as it is also recommended to avoid signal reflexion in 90° angles or even in octogonal routes. Anyway, we're not doing professional rated HiFi, aren't we ?
Did little routing improvements and cosmetic "cleaning" of the layout. I kept many values as well on silkscreen, because without them my previous bunch of three modules wouldn't have worked as Mouser BOM wasn't consistent and had wrong resistors. My mistake, I was too much confident in it.
Named it 5.3 but it could replace the former 5.2 if you prefer, as it isn't a big revision and maybe it will never see the sun...
