Features 1、This is a small MEMS microphone module with a range of about 50Hz‑15KHz, which can be used for almost all conventional audio recording and detection. 2、In addition to the three analog pins, there are three digital pins: clock, data and left and right (word selection) clock. 3、When connected to a microcontroller/computer, the I2S master device will drive the clock and word selection pins at a higher frequency, and read data from the microphone without analog conversion. 4、MEMS microphone can detect sound and convert it to voltage without analog conversion. 5、The left and right channels can be selected by connecting the Select pin to power or ground.
