An ESP32-based internet ESP32 radio with a touchscreen display
Arielhh on GitHub posts a fully functional internet radio based on an ESP32-S3 microcontroller. It was designed to work only with ESP32S3 Lilygo t-displayS3 Touch or an ESP32-S3 and 170×320 touch screen that share the same characteristics.
An I2S DAC is required for this project, Amplifier is optional. Consult the I2S data sheet to learn how to activate the (L+R)/2 or stereo signal.
Note: for some stations that don’t play and their URL starts with https:// try to change it to http:// and check if it is working.
Connection diagram using the Max98357a chip (if you use a header you don’t need to connect wires as the pins are arranged correctly). I strongly recommend using the PCM5102a for better sound quality.
