And it has done so all the way from China:
This package contained nothing less than the redesigned boards, professional made to order:
Dual layer printed circuit boards, 0.6mm thick, with black coating and red silkscreen (which is visible under the sun, but not so much indoors). Obviously we ordered some excess boards for redundancy and cost savings.
But from idea to a delivered product in less then two weeks (would be way less if some beginner mistakes were avoided), ordered from PCBCORE and totally worth it.
