SparkFun INMP401 MEMS Microphone Breakout features the ADMP401 MEMS microphone. One of the key advantages to this breakout and microphone is the bottom ported input. This means the microphone's input can fit flush against the enclosure of your project. Plus you will not have to deal with trying to solder the microphone's wacky footprint.
