SKU:A149
Atomic Echo Base is a voice recognition base designed specifically for the M5 Atom series hosts. It integrates the ES8311 mono audio decoder, MEMS microphone, and NS4150B power amplifier. The ES8311 provides 24-bit audio resolution and a sampling rate of 16KHz to 64KHz, supporting I2S communication and high-fidelity audio processing. The MEMS microphone with high signal-to-noise ratio and digital output is suitable for automatic voice recognition, while the built-in speaker ensures efficient audio output. The device supports full-duplex communication, allowing simultaneous sound transmission and reception, enhancing interactive functions such as voice recognition, wake-up, and recording playback, making it ideal for applications in smart homes and education.
