M5Stack Atomic Echo Base mit Mikrofon und Lautsprecher

The M5Stack Atomic Echo Base is an innovative development board specifically designed for the M5 Atom series. This module combines a state-of-the-art ES8311 mono audio decoder, a MEMS microphone, and an NS4150B Class-D amplifier to deliver outstanding audio quality with 24-bit resolution. The Atomic Echo Base enables full duplex communication, making it ideal for applications in voice recognition, wake-up functions, and audio playback. With a high signal-to-noise ratio of at least 65 dB, the microphone is particularly suited for automatic speech recognition. The compact design of the module facilitates integration into various projects, whether for smart home controls or educational applications. Additionally, the Atomic Echo Base supports popular development platforms such as UIFlow and Arduino, simplifying customisation to specific requirements.
