M5Stack Voice Pyramid Smart Speaker Base without M5Atom
Description
M5Stack Voice Pyramid is a desktop smart speaker base for M5Stack Atom series controllers, including Atom, AtomS3, and AtomS3R. It is supplied as a base without a controller and adds a larger acoustic structure, audio input and output, capacitive touch interaction, and RGB feedback for voice assistant and smart home projects.
The base combines an STM32G030F6P6 co-processor for touch and RGB control, an ES8311 audio codec, an ES7210 microphone acquisition chip with AEC, an AW87559 Class-D speaker driver, and a Si5351 programmable clock generator. It is intended for compatible M5Stack Atom series controllers; Atom Voice is not compatible with Voice Pyramid.
Notice: Do not use Voice Pyramid together with Atom Voice. M5Stack warns that this may result in device damage. The controller is not included with the Voice Pyramid base.
