3PCS ICS-43434 MEMS I2S Microphone Module, Omnidirectional Digital Mic, 24-bit, 120 dB AOP, 65dBa High-SNR, Low-Power Always-ON Mode, Compatible with ESP32, Raspberry Pi

Upgrade your projects with this 3-PCS ICS-43434 MEMS digital microphone module, engineered for high-fidelity audio capture and low-power operation. Featuring a 24-bit I²S digital interface, these microphones compatible with ESP32, Raspberry Pi, without requiring external ADCs or codecs. With a wide frequency response of 60 Hz – 20 kHz, a high Signal-to-Noise Ratio (65 dBA in performance mode), and a 120 dB Acoustic Overload Point (AOP), the ICS-43434 delivers clearer, more accurate audio across a broader range than basic MEMS microphone modules. The omnidirectional pickup ensures consistent detection from any direction, making it ideal for voice recognition, ambient monitoring, and audio recording applications. The low-power “AlwaysOn” mode enables continuous voice capture in battery-powered systems such as IoT devices, wearables, and smart home products, offering efficiency without sacrificing performance. Why choose ICS-43434? Wider frequency range: 60 Hz – 20 kHz (captures more detail in higher frequencies). Higher clarity: up to 65 dBA Signal-to-Noise Ratio in performance mode. Greater durability in loud environments: 120 dB SPL Acoustic Overload Point. Flexible power modes: including ultra-low-power “AlwaysOn” for voice-triggered designs. Whether you are upgrading from entry-level MEMS microphones or designing advanced IoT devices, the ICS-43434 provides superior audio performance, wider bandwidth, and more flexible power options, making it an excellent choice for demanding applications.

• High Performance Audio: The ICS-43434 Features 65 dBA SNR and an extended 60 Hz–20 kHz frequency response, 120 dB SPL Acoustic Overload Point, delivering clearer, more detailed sound for voice and ambient capture.
• Omnidirectional Pickup: ICS-43434 MEMS microphone breakout module captures clear audio from all directions, ideal for voice recognition and audio recording applications
• Wide Compatability: Seamlessly compatible with ESP32, Raspberry Pi through 24-Bit I2S(I²S) digital audio interface
• Versatile Applications & Durable Build: Perfect for voice recognition, smart home assistants, environmental monitoring, IoT devices, and portable audio recorders. Each module is built on a gold-plated (ENIG) PCB, ensuring reliable connections, corrosion resistance, and professional-grade sound capture in compact projects.
• Connect: By default, the LR pin is pulled down to GND via a 10kΩ on board resistor, selecting the Left (L) audio channel. To select the Right (R) channel, connect the LR pin to VDD.
• NEXT GENERATION MICROPHONE: The ICS-43434 delivers superior audio performance, replacing the discontinued INMP441 with higher SNR (65 dBA), extended 20 kHz bandwidth, stronger 120 dB SPL overload tolerance, and an ultra-low-power Always-On mode.
