Close Range / Low Volume I2S MEMS Microphone Breakout Board

Features :

• Flat wideband frequency response for high definition natural sound
• Digital output via I2S Serial
• Operating Voltage: 1.8V to 3.3V
• High signal-to-noise ratio  meaning it filters out noise well making it a good choice for close range audio pickup while filtering out background noise

• High precision 24-bit data
• Signal to noise ratio: 61 dBA
• Sensitivity: 26 dBFS
• Frequency response: 60 Hz to 15 kHz
• Current consumption 1.4 mA
• PSR: -75 dBFS

• Pinout:
• SCK: Serial data clock for I2S interface
• WS: Serial data word selection for I2S interface
• L/R: Left/Right channel selection.
• When set to low, the microphone outputs a signal on the left channel of the I2S frame.
• When set to high level, the microphone outputs signals on the right channel
• SD: Serial data output of the I2S interface.
• VCC: Input power, 1.8V to 3.3V.
• GND: Ground 0V
• Pin connection for use with ESP32 controllers:
• SCK >> GPIO14
• SD >> GPIO32
• WS >> GPIO15
• L/R >> GND
• GND >> GND
• VDD >> VDD3.3
• Works with ESP32 based microcontrollers and Raspberry Pis.
