DIY ESP32-S3 Internet Radio Features Winamp-Styled User Interface

Key Takeaways

• ESP32‑S3‑LCD‑1.54 board costs ~$15, enabling cheap radios.
• Arduino sketch provides Winamp‑style UI for streaming stations.
• Supports up to nine preset internet radio URLs.
• Uses ES8311 codec and NS4150B amp for decent audio.
• Project adaptable to other ESP32 boards with similar hardware.

Summary

Volos Projects released a DIY internet radio built around Waveshare’s ESP32‑S3‑LCD‑1.54 development board, priced around $15. The project uses an Arduino sketch featuring a retro Winamp‑styled interface and supports up to nine streaming stations. The board’s 1.54‑inch IPS display, ES8311 audio codec, and NS4150B amplifier deliver surprisingly good sound quality for the price. The design can be ported to other ESP32 platforms with minor pin‑mapping tweaks.

Pulse Analysis

The ESP32‑S3, Espressif’s latest Wi‑Fi‑and‑Bluetooth SoC, has quickly become a staple for low‑cost connected devices thanks to its dual‑core Tensilica LX7 processor, vector extensions for AI, and generous memory options. Waveshare’s ESP32‑S3‑LCD‑1.54 board packages this chip with a 1.54‑inch 240 × 240 IPS screen, USB‑C power, and a built‑in audio chain, all for roughly $15. By offering a ready‑to‑run Arduino sketch, Volos Projects transforms a development kit into a functional internet radio without requiring firmware expertise, showcasing how affordable hardware can be turned into market‑ready products in hours rather than weeks.

The radio’s user interface mimics the classic Winamp layout, delivering a nostalgic experience while leveraging modern touch‑free navigation. With support for up to nine preset streams, the sketch pulls audio through the ES8311 low‑power codec and NS4150B amplifier, producing clear playback that exceeds expectations for a board of this size. Because the code is open‑source and relies on widely available libraries such as LovyanGFX and esp32‑audio‑I2S, makers can easily add features like Bluetooth streaming, equalizer controls, or custom skins, extending the platform beyond a simple radio.

For the broader IoT ecosystem, this project illustrates a growing trend: commoditized microcontrollers paired with ready‑made software stacks are enabling rapid prototyping of consumer‑grade audio devices. Small startups can now prototype smart speakers, bedside alarms, or multilingual news readers at a fraction of traditional development costs, accelerating time‑to‑market. As ESP32‑S3 continues to receive firmware updates and AI‑accelerated capabilities, we can expect more sophisticated voice‑activated or edge‑processing audio applications to emerge, further blurring the line between hobbyist kits and commercial products.
