SparkFun Analog MEMS Microphone Breakout - SPH8878LR5H-1

The SparkFun Analog MEMS Microphone Breakout makes it incredibly easy to work with the high-quality SPH8878LR5H-1 analog microphone from Knowles. We designed this board with an integrated OPA344 OpAmp to boost the microphone's output to a usable level allowing you to plug directly into an ADC on a microcontroller or something like the SparkFun Spectrum Shield.The onboard OpAmp adds a bias voltage of 1/2 VCC to the audio signal. When capturing standard sound sources such as a normal speaking voice a few feet away the audio (AUD) output signal will register at about 200mV peak-to-peak. This helps provide a cleaner audio signal.Enclosure MountingTo help you build more professional enclosures the SPH8878LR5H-1 features a convenient bottom-port design.Flush Mounting: Because the audio port is located on the bottom of the sensor you can mount this microphone breakout completely flush against the outer surface of your project enclosure.Omni-Directional Sensing: The sensor excels at picking up sound from all directions making it an excellent choice for voice detection or ambient noise monitoring.Simple Connections: The board breaks out the essential VCC Ground and AUD pins making it easy to wire into your circuit.We designed this version of the Analog MEMS Microphone as a drop-in replacement so users with previous versions of this breakout board can incorporate it back into their projects without extensive rewiring or other system changes.
