  "textContent": "Designed for M5Stack Atom, AtomS3, and AtomS3R series IoT controllers based on ESP32 or ESP32-S3 wireless SoC, the Echo Pyramid base enables smart voice interaction applications such as far-field voice recognition, voice assistants, voice control, and more. The device features a built-in speaker, a MEMS microphone, an ES8311 HD audio codec for playback and capture, and an STM32 MCU for touch areas and RGB LED management. It’s powered via a USB Type-C port and can be expanded through a 4-pin connector for I2C modules. Echo Pyramic specifications: Supported IoT controllers – M5Stack Atom, AtomS3, and AtomS3R Microcontroller – STMicro STM32G030F6P6 32-bit Arm Cortex-M0+ CPU @ 64 MHz with 8KB SRAM, 64 KB flash Audio HD Codec – ES8311, handles playback and recording Microphone – LMA3729T381-0Y3S MEMS microphone ADC – ES7210 for microphone input Built-in speaker on the bottom of the pyramid Amplifier – AW87559 Class-D speaker driver for the speaker [...]\n\nThe post Echo Pyramid enables smart voice interaction applications on M5Stack Atom ESP32 IoT controllers appeared first on CNX Software - Embedded Systems News.",
