Analog MEMS Microphone Breakout - VM2020
The SparkFun Analog MEMS Microphone Breakout makes it easy to work with the Vesper VM2020 analog microphone. The VM2020 is an ultra-high Acoustic Overload Point (AOP), high dynamic range, differential analog output piezoelectric MEMS microphone. What separates this from other analog MEMS microphones is that it was designed to be used in loud environments.
This microphone breakout is differential and does not have an OpAmp. To connect to the differential output with an Arduino, you will need to amplify the signal to a usable level and ADC with differential inputs. We recommend using the SparkFun WM8960 Audio Codec Breakout with a built-in programmable gain amplifier and ADC.
