Description
This digital I2S MEMS Microphone works well with microcontrollers with I2S audio outputs like ESP32. Compared with traditional analog ones, this microphone features low noise, high sensitivity & reliability, and other excellent performances, which make it applicable to projects like voice recognition, recording, AI learning, Bluetooth audio transmission, and so on. This module uses surface mount MEMS I2S microphone sensor with top port, no components at the bottom, which can be embedded into various applications conveniently. Besides, DFRobot provides users with Arduino library for this product to allow them easily get started on ESP32.
