LM393 microphone module - Unit expansion module for M5Stack development modules

Unittype expansion module with omnidirectionalmicrophone, manufactured by M5Stack. It is compatible with theM5Stackfamily of development modules, which includes M5Stack Core, M5Atom and M5Stick. It features anLM393chip and aMAX4466amplifier to effectively suppress noise. It has sensitivity of52 dBand two outputs: analog and digital. The Unit communicates with the development module via theI2Cbus.Grovetype cables are used to connect the extension with the main modules. Dedicated connection cable is part of the kit.

• Programmable with popular platforms, which include UIFlow and Arduino
• Uses I2C bus to communicate with development modules
• Equipped with analog output and digital output
• Can be used in applications and projects whose mission is to display the FFT spectrum or record audio, switching voice with acoustic electrical conversion
• Equipped with two mounting holes, which are compatible with the LEGO system
