M5Stack A167 Voice Pyramid Smart Speaker Base
M5Stack A167 Voice Pyramid Smart Speaker Base without M5Atom is a functional base designed for smart voice interaction applications and built specifically for the M5Stack Atom series controllers. This pyramid offers plug-and-play convenience for rapidly building a high-performance audio interaction voice device. The A167 voice pyramid features an STM32G030F6P6 microcontroller that manages the dual capacitive touch-slider zones and RGB indicator LEDs. This pyramid supports an ES8311 high-performance audio codec (supports high-fidelity playback and capture) and an ES7210 microphone input acquisition with AEC echo cancellation. Typical applications include smart speakers and desktop voice assistants, voice control hubs, local/cloud voice interaction prototypes, and IoT voice gateways.
