Echo Pyramid

SKU:A167

Description

Echo Pyramid is a functional base designed for intelligent voice interaction applications. It is specifically built for the M5Stack Atom / AtomS3 / AtomS3R series controllers, featuring plug-and-play design to quickly build voice devices with high-performance audio interaction capabilities. By connecting an Atom series controller, the system handles audio data processing, wireless communication, business logic control, and IoT connectivity. It is suitable for far-field voice recognition, voice assistants, voice control, and various intelligent interaction scenarios.

The device integrates an independent STM32G030F6P6 microcontroller dedicated to managing the dual-side capacitive touch sliding areas and RGB indicator LEDs, enabling low-latency touch response and colorful, programmable lighting effects. Through intuitive touch interaction combined with rich visual feedback, users can easily perceive device status, voice interaction results, or system prompts, enhancing overall user experience and product expressiveness.

The audio system adopts the high-performance ES8311 audio codec, combined with ES7210 microphone input acquisition and AEC echo cancellation, achieving efficient acoustic echo cancellation, noise suppression, and clear far-field voice capture, providing reliable support for speech recognition and full-duplex interaction. The AW87559 high-efficiency Class-D speaker amplifier drives the built-in speaker to deliver clear audio output with excellent dynamic range. In addition, the system introduces the Si5351 programmable clock generator as the main clock source (MCLK), providing low-jitter and flexible clock signals for the audio ADC and DAC, effectively improving speech recognition accuracy and overall audio performance.

Echo Pyramid is suitable for development scenarios such as smart speakers, desktop voice assistants, voice control hubs, local / cloud-based voice interaction prototypes, and IoT voice gateways.
