Products from the USA may come with an input voltage of 110V–120V, requiring a step-down transformer. Check the device wattage to select the correct power converter.
•☺Small and Low Cost: This SPH0645 microphone breakout board is a small, low cost MEMS mic with a range of about 50Hz - 15KHz, good for just about all general audio recording / detection
•☺Attention When Connecting: Instead of an analog output, there are three digital pins: Clock, Data and Left-Right (Word Select) Clock. And these ports are very clearly marked making you very convenient when connecting
•☺With I2S Master: When connected to your microcontroller/computer, the “'I2S Master” will drive the clock and word-select pins at a high frequency and read out the data from the microphone
•☺With Dual Channel: The IIS microphone breakout module is a single mono element. You can select whether you want it to be on the Left or Right channel by connecting the Select pin to power or ground
•☺Can Output Stereo: If you need stereo, pick up two microphones! You can set them up to be stereo by sharing the Clock, WS and Data lines but having one with Select to ground, and one with Select to high voltage
