The design of this microphone is low-profile, with the port located on the bottom side. This allows the microphone to be mounted flush to the outer surface of an enclosure. The omnidirectional nature of the microphone ensures it captures sound sources effectively from all directions.
Unlike many other microphone breakouts in the SparkFun catalog, this one does not have an OpAmp. It instead offers a differential output. To connect this with an Arduino, the signal needs to be amplified to a usable level and ADC with differential inputs. The recommended device for this is the SparkFun WM8960 Audio Codec Breakout, which comes with a built-in programmable gain amplifier and ADC.
The SparkFun Analog MEMS Microphone Breakout is perfect for applications that require volume measurement in loud environments, audio capture next to speakers, fast Fourier transform analysis of sound at concerts, creation of electronic hearing protection, or adaptive filter development for smart speakers.
