This Atomic Echo Base is a voice recognition module made for the M5 Atom series and has audio input and output capabilities. It combines an ES8311 mono audio decoder, a MEMS microphone, and an NS4150B power amplifier to give a great audio experience.
The ES8311 supports 24-bit audio resolution and operates at sample rates from 16KHz to 64KHz, using I2S communication for level audio processing. The MEMS microphone provides a high signal-to-noise ratio (SNR), making it ideal for speech recognition. Paired with a built-in speaker, you can hear your voice with a clear sound output.
With full-duplex communication, the Echo Base can handle voice input and output simultaneously. This makes it well-suited for tasks like voice commands, speech recognition, wake-up functions, and real-time audio playback.
