ADMP401 MEMS Microphone omnidirectional
Description
This tiny breakout board contains the ADMP401 MEMS microphone. One of the main advantages of this breakout and the microphone is the bottom mounted input. This means that the input of the microphone can be flush with the case of your project.
The non-soldered pin headers make the application of these microphones variable.
