Compact Internet Radio with Touch Screen and WebUi

Description

🎧 What is it?

This is a fully working Internet Radio based on the ESP32-S3 microcontroller. It allows you to stream thousands of Internet radio stations from around the world — with no subscription fees, no licenses, and often fewer ads than traditional FM stations.

The device is battery-powered, portable, and includes:

• Touchscreen
• Built-in DAC and 3W Amplifier
• 5W Speaker

You can change stations and control the volume directly on the device, or remotely using the built-in web-based radio manager from a PC, Mac, or mobile phone.

Stations are accessed via online URLs. The radio can store up to 1000 favorites, and there are many free websites listing these URLs (see documentation).

🔧 Versions Available

• Fully Assembled Bluetooth Version Ready to use out of the box Including Bluetooth Transmitter for connecting to Bluetooth Speakers, headphones or earbuds. Just add a battery or power via USB-C, connect to Wi-Fi, and enjoy.
