I wanted a simple, easy to make wifi radio with only an ESP8266 and a speaker. The Code is not mine, but I want to show others how to make it running, because it is realy interresting to see the possibilitys the ESP8266 actualy has.

EXPANDED TECHNICAL DETAILS

High-Speed Audio Streaming

This project transforms an ESP8266 (like the NodeMCU) into a standalone internet radio station.

  • I2S Audio Pipeline: The ESP8266 connects via WiFi to an internet radio stream (e.g., Icecast). It uses the ESP8266Audio library to decode the MP3/AAC stream and output digital audio via I2S to an external DAC (like the MAX98357A).
  • Buffer Management: Implements a jitter buffer in the ESP8266's limited RAM to ensure stable playback even during minor network fluctuations.

User Interface

  • Station Presets: Multiple radio URLs are stored in the device's LittleFS or SPIFFS file system, allowing the user to switch channels using a physical rotary encoder.
