Product description
MEMS Microphone with I2C, a compact breakout board featuring the digital MEMS microphone SPH0645LM4H. The module uses an I2S interface and is suitable for projects where you want to capture audio directly to a microcontroller or single-board computer without analog signal processing. It is suitable for voice control, sound detection, recording, and other audio-based applications. The microphone has a bottom port and should be mounted so the sound opening is directed toward the sound source.
The board is compatible with development boards with I2S support, such as Raspberry Pi, ESP32, and other microcontrollers with built-in I2S support. For stereo solutions, two modules can be used together where the left or right channel is selected via the Select pin.
Pin header included (not pre-soldered) for connection to e.g. breadboard.
