Internet radio based on ESP32, VS1053 and a TFT screen. Will compile in Arduino IDE. The 28-jul-2017 is a major update. You MUST include the GPIO pin assignments in the preferences. See the documentation and/or the defaultsettings in the config page of the webinterface.


  • Can connect to thousands of Internet radio stations that broadcast MP3 or Ogg audio streams.
  • Can connect to a standalone mp3 file on a server.
  • Support for .m3u playlists.
  • Can play mp3 tracks from SD card.
  • Uses a minimal number of components; no Arduino required.
  • Handles bitrates up to 320 kbps.
  • Has a preset list of maximal 100 favorite radio stations in configuration file.
  • Configuration (preferences) can be edited through web interface.
  • Can be controlled by a tablet or other device through a build-in webserver.
  • Can be controlled over MQTT.
  • Can be controlled over Serial Input.
  • Can be controlled by IR.
  • Can be controlled by rotary switch encoder.
  • Can be controlled by touch pins.
  • Up to 14 free input pins can be configured to control the radio.
  • The strongest available WiFi network is automatically selected.
  • Heavily commented source code, easy to add extra functionality.
  • Debug information through serial output.
  • 20 kB ring buffer to provide smooth playback.
  • Software update over WiFi possible (OTA).
  • Bass and treble control.
  • Saves volume, bass, treble and preset station over restart.
  • Configuration also possible if no WiFi connection can be established.
  • Can play iHeartRadio stations.
  • Displays time of day on TFT.
  • Optional display remaining battery capacity on screen.

See documentation in doc/pdf-file.
