Audio-3.5 Base Voice Recognition and Audio Playback Base for Atom Series Controllers

Audio-3.5 Base Voice Recognition and Audio Playback Base for Atom Series Controllers Popis

Audio-3.5 Base is a voice recognition and audio playback base designed for the Atom series controllers (not compatible with Atom Voice).
It integrates an ES8311 mono audio codec, a MEMS microphone, and an NS4150B power amplifier, equipped with a standard 3.5mm audio jack and a 4-segment TRRS connector (CTIA standard) to support both audio output and microphone input.
The ES8311 supports 24-bit audio resolution with a sampling rate range of 16kHz ~ 64kHz and communicates via the I2S interface, enabling high-fidelity audio processing.
The onboard MEMS microphone offers a high signal-to-noise ratio and digital output capability, optimized for automatic speech recognition scenarios, while the integrated speaker delivers efficient audio output.
This base supports full-duplex communication for simultaneous audio transmission and reception, making it suitable for applications such as voice assistants, voice control terminals, home voice gateways, and voice interaction devices.
