For the record, you could also use a much cheaper MCU like e.g. an STM32F030C6 which costs around $0.60 for a single chip and around $0.45 for 30 chips at LCSC the moment. Of course this is completely irrelevant if you build a small number of boards like here, because then you'll probably waste most time with programming the chip and you need the necessary programming connector + tools too. It would be fun to redesign this board for the lowest manufacturing cost with machine assembly and compare it to how much more expensive it would be to use discrete logic chips. |
