TECNOULAB 5pcs GY-MAX4466 electret microphone amplifier MAX4466 adjustable gain module

【MAX4466】 GY-MAX4466 Electret Microphone Amplifier MAX4466 Adjustable Gain Module. Add an earful to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. 【Compact design】For amplification we use Maxim MAX4466, an operational amplifier designed specifically for this delicate task. The amplifier has excellent power supply noise rejection. 【High Performance】This breakout is best used for projects such as voice changer, audio recording and reactive audio projects using FFT. On the back we include a small potentiometer to adjust the gain. 【Resolutions】You can set the gain from 25x to 125x. This drops to about 200 mVpp (for normal speaking volume at about 6 inches away), which is useful for connecting to something that expects a clipless "line-level" input. 【High Performance】Up to approximately 1 Vpp, ideal for reading from an ADC microcontroller. The output is rail to rail, so if the sound gets loud, the output can reach up to 5 Vpp.
