Atomic Echo Base with Microphone and Speaker
Description The Atomic Echo Base is a voice recognition base designed specifically for the M5 Atom series. It uses an integrated solution with the ES8311 mono audio decoder, MEMS microphone, and NS4150B power amplifier. The ES8311 offers 24-bit audio resolution and a sample rate of 16KHz to 64KHz, supporting I2S communication and high-fidelity audio processing. The MEMS microphone with high signal-to-noise ratio (SNR) is suitable for automatic speech recognition, while the built-in speaker ensures efficient audio output. The device supports full-duplex communication, enabling simultaneous voice transmission and reception, enhancing interactive features such as speech recognition, wake-up, and audio playback. It is ideal for applications in smart homes and education.
