- HIGH-SENSITIVITY DIGITAL I2S OUTPUT: Features the INMP441 MEMS microphone, delivering high-performance audio with a high signal-to-noise ratio. The digital I2S interface simplifies your circuit design by providing a direct, high-fidelity audio stream, while the flat wideband frequency response ensures natural, high-definition sound reproduction ideal for near-field applications.
- BROAD MICROCONTROLLER COMPATIBILITY: Engineered for seamless integration with a wide range of development boards. It is an excellent choice for ESP32-based projects and is fully compatible with other microcontrollers that support the I2S protocol, making it a versatile audio input solution for your electronic creations.
- IDEAL FOR VOICE AND SOUND-REACTIVE PROJECTS: The omnidirectional pickup pattern and high sensitivity make this module perfect for applications requiring ambient sound detection. Excel in projects like sound-reactive WLED lighting, DIY smart speakers for platforms like Home Assistant, voice command systems, and other audio-interactive devices.
- COMPACT AND EFFICIENT DESIGN: Built for projects where space and power are at a premium. The ultra-small 4.72 x 3.76 x 1 mm surface-mount package and low power consumption allow for easy integration into mobile devices, laptops, gaming consoles, and compact security systems without impacting battery life or board layout.
- RELIABLE SURFACE-MOUNT CONSTRUCTION: This module is designed for durability and ease of manufacturing, being reflow-solder compatible without sensitivity degradation. It is also halide-free, ensuring compliance with modern electronics standards. We provide comprehensive after-sales support: complete digital documentation including user guides and technical references is available through our store customer service, and our support team is ready to assist with installation, programming, and troubleshooting to help you get started quickly.
