Build Smarter Interfaces: ESP32-S3 with 4” Display, Wi-Fi, Bluetooth & CAN FD

Looking to build an advanced HMI, diagnostic tool, or industrial control panel with cutting-edge connectivity and sleek graphics? Meet our ESP32-S3 4" 480x480 IPS LCD Board, a powerhouse designed for developers and engineers who demand performance, versatility, and ease of integration.

Feature-Packed for Modern Applications

At the heart of this board is the Espressif ESP32-S3-WROOM-1U-N16R8, a powerful module featuring:

• Dual-core Xtensa® LX7 processor running at up to 240 MHz

• 16 MB of flash memory and 8 MB of PSRAM

• Support for Wi-Fi, Bluetooth Classic, and Bluetooth Low Energy (BLE) via an external u.FL antenna connector (antenna not included)

• Integrated AI acceleration instructions—perfect for edge computing tasks like gesture recognition or speech processing

This module provides the backbone for complex applications in industrial automation, IoT systems, smart appliances, and more.

Built-in Support for Both Classical CAN and CAN FD

Versatile communication is a top priority for industrial and automotive systems, and this board doesn’t disappoint:

• Classical CAN support is provided directly via the ESP32-S3’s internal controller, available on connector J6

• CAN FD (Flexible Data-rate) is enabled through a Microchip MCP2518FD connected via SPI, accessible on connector J5

With both interfaces at your fingertips, the board is ideal for applications that require backward compatibility with existing CAN 2.0B systems as well as forward-looking CAN FD integration.

Stunning 4" Touch Display

The device includes a high-resolution 4.0” 480x480 IPS LCD with capacitive touch, offering:

• Wide viewing angles and vivid color representation

• Multi-touch input for modern, intuitive UIs

• A responsive interface ideal for handheld tools, HMIs, and user dashboards

Whether you're building a smart thermostat, vehicle dashboard, or industrial touch controller, the display ensures clarity and responsiveness.

UI Development Made Easy: LVGL + SquareLine Studio

Creating a polished user interface no longer requires months of development. This board supports:

• LVGL (Light and Versatile Graphics Library): An open-source graphics library known for its efficiency, customizability, and smooth performance on embedded systems

• SquareLine Studio: A visual UI editor that integrates seamlessly with LVGL, making it easy to drag-and-drop UI components and generate production-ready code

From buttons and charts to animations and complex layouts, your design workflow is faster and more intuitive than ever.

Designed for Innovation

Whether you're developing automotive diagnostic tools, industrial machinery dashboards, smart home controllers, or custom HMI interfaces, this board provides:

• Advanced wireless and wired connectivity

• Stunning graphics and responsive input

• AI-capable processing and ample memory resources

• Support for dual CAN protocols

• A solid foundation for scalable product development
