The module is manufactured by the SparkFun company with an analog microphone made in the MEMS SPH8878LR5H-1 technology. The board is equipped with OpAmp, thanks to which it is possible to connect it directly to the ADC of the microcontroller, e.g. the Arduino module. SparkFun Analog MEMS Microphone Breakout includes an omnidirectional microphone that captures sounds coming from different directions well. The signal-to-noise ratio of the microphone is 66 dBV / Pa.
