From the article under "Manufacturing plan"- "We will outsource PCB fabrication and assembly to PCBWay and handle final programming and testing ourselves, here in Cambridge UK. We have developed a programming jig, along with a suite of extensive automated tests to speed things up." To sell from outside China and make a profit it is still difficult. I work with a project that had nearly identical production model (not PCBway but another CM) and when the US tariffs came about it was a major hit. A lot of manufacturers skirt these tariffs through various means (none legal) as well as produce without having to produce IP in house or pay staff for further development...both of which create a significant amount of profit which often cannot be accrued by a small project/team on it's own. Saying "They could do it cheaper..." is often the response from those who are used to alibaba prices. There is a lot more to consider in those cases. When you start to actually get into production you quickly learn that you cannot (and shouldn't bother) competing with offshore production (and cloning). Just set the price and make the product. The real problems start when your project becomes popular enough to be copied. This is all much more difficult when the hardware is OSHW (as ours is).
