What is the use of this product? Let’s start by saying that it doesn’t require any soldering with the microphone’s footprint, it allows the input of the microphone to fit flush against the project of yours since the perfect feature it has is the bottom ported input advantages to this breakout and microphone
Some of the amplifier’s features include the following points:
• The amplifier on the breakout has a gain of 67 and more than meets the bandwidth requirements of the mic
• The amplifier’s AUD output will float at one half Vcc when no sound is being picked up
• The amplifier produces a peak-to-peak output of about 200mV when the microphone is held at arm’s length and is being talked into at normal conversational volume levels
Which gives the following conclusion: The AUD output can easily be connected to the ADC of a micro.
