How’s $0.03 for a microcontroller? :) https://www.youtube.com/watch?v=VYhAGnsnO7w <https://www.youtube.com/watch?v=VYhAGnsnO7w>

By the way, lcsc.com <http://lcsc.com/> where this mcu came from is a really interesting distributer, part of the same company als jlcpcb.com <http://jlcpcb.com/> (pcb manufacturer). Lots of cheap Chinese parts, but also e.g. ST microcontrollers for better prices than e.g. Farnell or Digikey. I’ve used some of them in production, no complaints yet.
