NeutronNed has developed a microphone module for Teensy – great for wearable sound reactive projects. You can buy it on Tindie for under $10. There is some great discussion over on the forum.

Here’s a nifty test video by forum user Potatotron

This module is designed for Teensy boards and has the proper signal voltages for use with the audio library.  It uses the MAX9814 – a high quality, now noise, pre-amp chip.  This module is designed to work directly with the Teensy analog inputs – you don’t need the audio shield to use this module.

If you are doing any project that requires a microphone and a Teensy, go buy this now.
