M5Stack Atomic Audio 3.5 Base
The M5Stack Atomic Audio-3.5 Base adds high-quality voice recognition and audio playback to Atom series controllers, featuring a 3.5mm TRRS audio jack, MEMS microphone, ES8311 audio codec, and full-duplex audio support for smart voice interaction projects.
The M5Stack Atomic 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, smart home voice gateways, and voice interaction devices.
Features
- 3.5mm audio jack supporting audio output + microphone input
- Integrated ES8311 high-fidelity audio codec with 24-bit high-resolution audio processing
- Full-duplex voice communication with simultaneous audio send and receive
- Auto-switching functionality
