This is a breakout board for our electret microphone with a supporting amplifier attached to an iPod connector. The output of the amp is wired to the audio input pin of an iPod. This microphone could be used with a custom application on the iPod Touch, allowing the user to add a microphone to their iTouch.
The output of the amplifier is a 400mV peak-to-peak wave which is the standard voltage level for line-in audio.
