Does anyone know how they are able to produce such a powerful chip so cheaply? Do they use Chinese fabs?



Moore's Law is incredibly powerful. It's a 400MHz microprocessor that's roughly equivalent to a late-nineties desktop PC, the sort that could (with a suitably fast CDROM drive) just about manage to decode to 320x200 VGA resolution. This is still a really impressive feat of coding.

Fab appears to be TSMC. So, the Republic of China?


No, it's manufactured by TSMC (Taiwan)


Expressif is based in Shanghai. I would think so but I don't know how to check.
