Description
Node, like its namesake, is a smart node with full-featured functions in a IoT application scenarios. Together with M5Stack Core, it can be programmed as an intelligent speaker like Echo. Node provides more hardware resources: built-in high-fidelity audio codec chip，MIC, DHT12, IR
ESP32 provides an Audio Develope Platform called ESP-ADF. ESP-ADF supports development of audio applications for the Espressif Systems ESP32 chip in the most comprehensive way. With ESP-ADF, you can easily add features, develop audio applications from simple to complex:
- Music player or recorder supports audio formats such as MP3, AAC, FLAC, WAV, OGG, AMR, TS, EQ, Downmixer, Sonic, G.711, SPEEX ...
- Play music from sources: HTTP, HLS(HTTP Live Streaming), SPIFFS, SDCARD, A2DP-Source, A2DP-Sink, HFP ...
- Integrate Media services such as: DLNA, WeChat ... Internet Radio
- Voice recognition and integration with online services such as Alexa, DuerOS, and more.
This product is EOL now, we've released the updated version ATOM Echo Smart Speaker Development Kit which is fully compatible with this product.
