Specifically tailored for M5Stack's Atom series (excluding Atom Voice) controllers, it offers plug-and-play functionality to quickly build voice devices with high-performance audio interaction capabilities. By connecting an Atom series controller, users can achieve audio data processing, wireless communication, business logic control, and IoT connectivity. It is suitable for various smart interaction scenarios such as far-field voice recognition, voice assistants, and voice control. The device features a built-in independent **STM32G030F6P6** microcontroller, dedicated to managing the bilateral capacitive touch sliding areas and RGB indicator lights, enabling low-latency touch response and colorful, programmable light feedback. Through intuitive touch operations combined with rich visual indications, users can easily perceive device status, voice interaction results, or system prompts, enhancing the overall user experience and product expressiveness. The audio system utilizes the high-performance **ES8311** audio codec, paired with **ES7210** microphone input acquisition + AEC (Acoustic Echo Cancellation), achieving efficient echo cancellation, noise suppression, and clear far-field voice capture, providing a reliable guarantee for voice recognition and full-duplex interaction. Driven by the **AW87559** high-efficiency Class-D speaker driver chip, the built-in 5W @ 3Ω speaker delivers clear audio output with excellent dynamic range. The system incorporates the **SI5351** programmable clock generator as the master clock source (MCLK), providing low-jitter and flexibly configurable clock signals for the audio ADC and DAC, effectively improving voice recognition accuracy and overall audio performance. @@ -16,4 +16,4 @@ Echo Pyramid is ideal for development scenarios such as smart speakers, desktop ## License -- [M5Echo-Pyramid](https://github.com/m5stack/M5Echo-Pyramid/blob/main/LICENSE) \ No newline at end of file +- [M5Echo-Pyramid](https://github.com/m5stack/M5Echo-Pyramid/blob/main/LICENSE)
