About this item

The DFRobot Fermion: MEMS Microphone Module is a compact, high-performance digital microphone module designed for capturing clear, low-noise audio in embedded and IoT applications. Built around a MEMS (Micro-Electro-Mechanical System) sensor, this module offers excellent sensitivity and reliability in a miniature package, making it ideal for voice recognition, sound detection, and environmental monitoring projects. With a digital I²S output interface, the Fermion MEMS Microphone is optimized for seamless integration with microcontrollers and single-board computers like Arduino and Raspberry Pi. It supports left/right channel selection, allowing stereo setups using multiple modules. The onboard voltage regulator and level shifter make it compatible with both 3.3V and 5V systems. Thanks to its wide frequency response and high signal-to-noise ratio (SNR), it can capture both low and high-frequency audio clearly. Whether you're building a smart speaker, voice-controlled robot, or sound-activated lighting system, this module provides a solid foundation for accurate audio input. Lightweight and breadboard-friendly, the Fermion MEMS Microphone Module offers plug-and-play ease of use while delivering professional-grade performance for makers, students, and developers working on sound-related embedded projects.
