M5Stack Echo Pyramid Smart Speaker Base for Atom Series

The Echo Pyramid Smart Speaker Base transforms your M5Stack Atom series controller into a sophisticated voice interaction device. This innovative base features a dedicated STM32G030F6P6 auxiliary MCU that manages touch controls and RGB lighting, while the ES8311 high-performance audio codec delivers exceptional sound quality for both playback and recording. The integrated ES7210 microphone with AEC echo cancellation ensures crystal-clear voice capture, even in challenging acoustic environments. An AW87559 high-efficiency amplifier drives the built-in speaker, producing robust audio output. The base includes 28 WS2812 RGB LEDs arranged in seven-LED strips on each side, creating dynamic visual feedback.

Dual-side capacitive touch-slider zones with four detection points provide intuitive control options. The compact design measures 3.29 x 3.29 x 2.23 inches and weighs just 3.55 ounces. A Grove expansion port enables additional I2C connectivity for extended functionality. Operating on 5V DC power, this base is ideal for building voice assistants, smart home controllers, and far-field voice recognition systems. Compatible with Atom, AtomS3, and AtomS3R series controllers (sold separately), it offers plug-and-play convenience for rapid prototyping and deployment of audio interaction applications.
