Introduction

The ESP32-S3 Round Display Development Board is a powerful, all-in-one platform engineered for creating sophisticated visual and interactive applications. It builds upon a feature-rich ESP32-S3 core by integrating a vibrant, 1.85-inch circular touchscreen directly onto the board. This development board is packed with features beyond the display, including Wi-Fi & Bluetooth connectivity, onboard audio for AI voice interaction, and convenient Qi wireless charging. This high level of integration simplifies the entire development process for complex projects like smart home control panels, industrial HMIs, and custom wearable prototypes, allowing developers to focus on what truly matters: the software and user experience.


High-Performance ESP32-S3 Core

At the core of this development board lies a powerful ESP32-S3R8 dual-core processor, running at a main frequency of up to 240MHz. This robust processing power is complemented by a generous memory configuration, including 8MB of PSRAM and 16MB of Flash. This combination gives the board the resources to handle demanding tasks, render complex graphical user interfaces like LVGL smoothly, and execute AI algorithms for voice and sensor data processing.
