Base Node

SKU:M017

Description

Base Node is an IoT smart node base. It comes with built-in high-fidelity audio decoding chips, a microphone, DHT12, IR transceiver, LED lights (SK6812), and other hardware resources. When used in conjunction with M5Core, it supports multi-node terminal interconnection, device control, and information transmission.

Not only that, the powerful Base Node is also suitable for smart audio device development. Using M5Core as the control core and leveraging the ESP-ADF audio development platform provided by ESP32, it enables comprehensive audio application development for the Espressif Systems ESP32 chip. Rich application cases can guide you step-by-step in adding new features, completing audio application functionalities from simple to complex:

• Supports multiple audio formats such as MP3, AAC, FLAC, WAV, OGG, AMR, TS, EQ, Downmixer, Sonic, G.711, SPEEX, etc.
• Multiple audio playback sources: HTTP, HLS (HTTP Live Streaming), SPIFFS, SDCARD, A2DP - Source, A2DP - Sink, HFP, etc.
• Integrated media services such as DLNA, WeChat, Internet Radio, etc.
