Of course it works. Nothing Chinese there, all ICs and passives from foreign manufacturers. I can also see differential pairs, properly terminated comm trace ends, nicely spaced routing, high quality nylon connectors etc etc. All highly professional stuff, Joe biden would prolly disagree though, but then his cult is the cult to be!

MESA is open source, not chinese man. Just happens that this dude kindly/generously provides a full "turn-key" solution to the community.

All the best of luck.
