CentIoT - GY-MAX4466 adjustable electret microphone amplifier module MAX4466

Brand: CentIoT

Features:

• This breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT
• Gain Adjustable from 25x to 125x
• Power Supply: VCC to 2.4 - 5 VDC (can use arduin 3.3v)
• The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled)
• For the amplification, the module has built in Maxim MAX4466

PartNumber: AE008-GY-MAX4466

Details: Description This breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6" away) which is good for attaching to something that expects 'line level' input without clipping, or up to about 1Vpp, ideal for reading from a micro controller ADC. The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp! Using it is simple: connect GND to ground, VCC to 2.4-5VDC. For the best performance, use the "quietest" supply available (on an Arduin, this would be the 3.3V supply). The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required. The output pin is not designed to drive speakers or anything but the smallest in-ear headphones - you'll need an audio amplifier (such as our 3.7W stereo amp). Note: 1. If the audio equipment you're using requires ac coupled audio, place a 100uf capacitor between the output pin and the input of your device 2. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uf cap is not required 3. The output pin is not designed to drive speakers or anything but the smallest in-ear headphones - you'll need an audio amplifier
