Product description: MEMS PDM Microphone - Unit extension module for M5Stack development modules
MEMSdigitalmicrophonebased on PDM(Pulse Density Modulation) signal.Unittype module dedicated forM5Stackproducts. It has radio frequency interference, high signal-to-noise ratio andhigh sensitivity. Additionally, it consumes relativelysmall amounts of energyand has 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 theI2S interface.
The subject of sale is mMEMS PDM iconphone - Unit type module for M5Stack series.
TheM5Stackdevelopment module must be purchased separately.
