SPH0645LM4H Microphone module I2S interface

The SPH0645LM4H microphone is a mono microphone that can be connected to the left or right of the device. If the system needs to operate in stereo, two of these microphones must be obtained, and the clock, WS, and data lines should be shared, with their grounds connected to each other. The communication protocol of the SPH0645LM4H microphone module is performed via the I2S interface and is powered by a 3.3V supply. Therefore, make sure that your microcontroller supports the I2S interface before purchasing. This module is compatible with Cortex M series chips, Arduino, and Raspberry Pi.
