AJMRTC ICS43434 I2S digital microphone module is a high-performance MEMS microphone accessory for Xiaozhi AI voice systems. It outputs 24-bit digital audio via I2S (IIS) interface and is functionally interchangeable with INMP441 microphone modules. Integrated with MEMS sensing element, ADC and digital filter, it can directly output digital audio signals to MCUs without additional analog audio codec. It runs at 3.3V low voltage with low power consumption, high signal-to-noise ratio and excellent acoustic overload resistance. It supports clear voice capture for voice recognition, speech command and audio sampling. Widely used for ESP32 Xiaozhi AI voice projects, smart speakers, voice trigger devices, microphone arrays and embedded audio collection applications. Please only supply 3.3V power; 5V input will damage the module.
