  • The sound port of the microphones is on the bottom of the package (see the two holes in the bottom of the PCB). You could think of the holes on the bottom as the microphone sound input, so the board 'listens' to acoustic inputs coming from the bottom - the opposite side of the board from the processor.

  • This was educational as well as entertaining. As engineers, I think we are reluctant to talk about 'how the sausage gets made'. Thanks for the article.
