mitxela used a CH32V003 in these earrings, which (i think?) would work with Embassy by way of ch32-hal, but the footprint might be a bit too large to fit in the barbell.
Oooh I think I misunderstood. If you're talking about putting it in a barbell and being able to remove it for charging or whatever, that becomes easier.
there’s probably (maybe?) a micro you could fit into this design but i don’t think i’d be comfortable putting it through anatomy that’s gonna get handled aggressively.

things get harder once you move outside of those standards or need to implant a power source

I thought you meant IN the nipple, not through it
although if you’re willing to go with a ring or a chain hanging off the barbell that would probably work & look awesome.
