MAX9814 is an Adafruit manufacturer's microphone with amplifier module. It instantly connects the microphone to the amplifier so the user can use it instantly in their projects without the complicated search for matching the amplifier and microphone. The microphone works by converting the vibration of the plate due to sound waves into an electrical signal amplified by an amplifier specially selected for audio signals of various volumes, so that closer loud sounds do not obscure further weak sounds, and sound gain is performed automatically. That signal can already be transmitted to the analog connector of the microcontroller.

Technical data:
● The gain can be changed by physical connections (60 dB, 40 dB, 50 dB).
● Signal type: analog
● Supply voltage: 3.3V DC
● Frequency range: 20 Hz to 20,000 Hz
● Dimensions: 26 x 14 mm
