LOL... Bit hard to sandpaper under some of those connectors!
Anyway, yes, the Ethernet/USB edge is machine cut on both boards. The other 3 are scored and snapped. Just one board doesn't seem to be as deeply scored before snapping leaving it a bit rough. Maybe the blade was wearing out.
Anyway, they both work fine, and if the composite connector causes any issues with a case (or just annoys me too much when I look at it) I'll warm out the hot-air rework station and straighten it out
I was just curious if anyone else had noticed a lower quality on one source vs the other.
I've got a third board arriving any day now, it will be interesting to compare.
