PDM Microphone Unit - Unit expansion module for development modules M5Stack
MEMSdigital microphone based on PDM signal. Unit type module dedicated for M5Stack products. It has radio frequency interference, high signal-to-noise ratio and high sensitivity. Additionally, it consumes relatively small amounts of energy and has a smooth frequency characteristics. The state of the microphone switches automatically according to the clock frequency (switch off/activate/sleep). The module can be used to collect digital data on mobile devices and smart digital devices. Communication takes place via the I2S interface.
