ESP32-Radio

Please use the V2 version of the ESP32-Radio.

See https://github.com/Edzelf/ESP32Radio-V2

Internet radio based on ESP32, VS1053 and a TFT screen. Will compile in Arduino IDE. See the review by Andreas Spiess at https://www.youtube.com/watch?v=hz65vfvbXMs.

Look for documentation and printdesign in the doc directory.

Features:

• 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 or USB stick (CH376).
• 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.
• Uses a 12 kB queue to provide smooth playback.
• Software update over WiFi possible (OTA) through Arduino IDE or remote host.
• 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.
• PCB available (see doc).
• 3D case available (see doc).
