Description
The module is equipped with electret microphone in the range from 20 Hz to 20 kHz and MAX4466 amplifier with automatic gain control. The intensity of the work in the amount of 2.4 V to 5 V. It has the ability to adjust the gain from 25x to 125x.
The heart of the module is the amplifier MAX644. It has the ability to adjust the gain from 25x to 125x.The output is about 200 mVpp or 1 Vpp, perfect for reading with a microcontroller ADC. Output rail-to-rail, so if the volume is increased the output may be increased to 5 Vpp.
