All electronics ship with US style plugs.You may need a voltage converter or a plug adapter.
Special Features
Application: the MAX4466 microphone breakout is suitable for voice converters, audio recording and sampling, and audio response projects using FFT; On the back, there is a small trimmer pot to adjust the gain; You can set the gain from 25x to 125x
Parameters: power supply voltage: +2.4V to +5.5V (can be compatible with STM, Raspberry Pi and other development board motherboards); Power supply rejection ratio: 112dB;
Common mode rejection ratio: 126dB; AVOL: 125dB (RL = 100 thousands of ohm meter) rail-to-rail output; Quiescent power supply current: less than 24 microamp; Gain bandwidth: 600kHz
20-20KHz electret microphone soldered on: comes with a 20-20KHz electret microphone soldered on the board for audio-reactive projects; It is recommended to use the FFT driver library, which can take audio input and 'translate' it into frequencies

Description
Introduction:
Connect GND to ground, VCC to 2.4-5VDC.
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 3.7W stereo amp)
If you want to connect the amp directly to speakers. If you're connecting to a microcontroller pin, you don't need an amplifier or decoupling capacitor - connect the OUT pin directly to the microcontroller ADC pin.
For audio-reactive projects, we suggest using an FFT driver library which can take the audio input and 'translate' it into frequencies.
