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.
