E-outstanding MAX4466 Electret Microphone Amplifier GY-MAX4466 Adjustable Gain Amplifier Module for Arduino With excellent power supply noise suppression ability, it can add color to your project. The evaluation board has a welded 20-20KHz electret microphone. Ground the GND, connect the VCC to 2.4-5vdc, for best performance, use the Suitable for projects using FFT, such as voice converters, audio recording amplifiers and audio response projects. On the back, we include a small trim potentiometer to adjust the gain, which you can set from 25 to 125. Package includes: 1pc Electret microphone amplifier MAX446. Voltage: 2.7V-5.5V The fully assembled and tested circuit board has a 20-20KHz electret microphone. For zooming, we use specially designed for this delicate task! The amplifier has excellent power supply noise rejection, so the amplifier sounds really good. This breakthrough is most suitable for projects that use FFT, such as voice converters, audio recording amplifiers, and audio response projects. On the back, we include a small trimmer potentiometer to adjust the gain. You can set the gain from 25 times to 125 times. Down to about 200mVpp (for normal voice, the distance is about 6 inches), which is great for connecting to something that expects a "line level" input without clipping, or up to about 1Vpp, which is great for reading from a microcontroller ADC . The output is track-to-track, so if the sound becomes louder, the output can be as high as 5Vpp! Instructions: GND is grounded, and VCC is grounded 2.4-5VDC. The audio waveform will be output from the OUT pin. The output will have a DC bias of VCC/2, so when it is completely quiet, the voltage will be a stable VCC/2 volts (DC coupled). If the audio device you are using requires AC-coupled audio, please place a 100uF capacitor between the output pin and the input of the device. If you want to connect to an audio amplifier that has a differential input or includes a decoupling capacitor, you don't need a 100uF capacitor. Shipping We offer FREE shipping on all orders!
