FM Transmitter: Please help decode diagram/power properly (Mandarin or Catonese would be helpful) Answered
I just need to figure out how to power this thing!
Notice the positive marks in both upper corners, the negative in both lower?
The large circle is the microphone, which is fully wired. The smaller circle is the frequency modulation, which is all set as well.
The underside only has holes where the gray squares are and is otherwise clean (exception being one spot where the two mounting prongs of the microphone pushed through.)
