Description
The **ESP32-S3 SI4732 Pocket Multiband Receiver** is a compact, feature-rich radio receiver project that utilizes the **Lilygo T-Display S3** development board. This device is powered by an ESP32-S3 microcontroller and integrates a **1.9-inch ST7789 IPS display**, making it a versatile platform for radio enthusiasts. The project is based on an open-source sketch developed by Ralph Xavier, which transforms the hardware into a fully functional multiband radio capable of receiving **LW (longwave), MW (medium wave), SW (shortwave)** in both **AM and SSB (single sideband)** modes, as well as commercial FM stations.
