This board is powered by the Espressif ESP32-S3-WROOM-1U-N16R8 module, a high-performance SoC featuring integrated Wi-Fi, Bluetooth Classic, and Bluetooth Low Energy (BLE). Wireless connectivity is achieved through an external antenna (not included), connected via a u.FL connector, providing flexibility in placement and signal optimization.
The ESP32-S3 is built on a dual-core Xtensa® LX7 processor, operating at up to 240 MHz, and includes 16 MB of flash and 8 MB of PSRAM, enabling complex applications and rich user interfaces. It supports AI acceleration for certain edge computing tasks, thanks to its built-in vector instructions and hardware-accelerated neural network operations.
Connectivity Features:
-
Classic CAN interface is natively supported by the ESP32-S3, accessible via connector J6, allowing communication with legacy CAN 2.0B networks.
-
CAN FD support is provided through a dedicated Microchip MCP2518FD controller connected via SPI, available on connector J5, enabling higher data rates and larger payloads in modern automotive and industrial networks.
Display and UI:
The board is equipped with a 4.0-inch 480x480 IPS LCD panel featuring capacitive multi-touch input for an intuitive and responsive user experience. The display supports high color fidelity and wide viewing angles, making it ideal for modern HMI applications.
-
Graphics rendering is handled by the powerful and lightweight LVGL (Light and Versatile Graphics Library), which enables smooth, responsive, and customizable interfaces.
-
UI design is streamlined with SquareLine Studio, a visual development environment that integrates seamlessly with LVGL, allowing developers to create professional-grade UIs with ease.
This board is ideal for developing industrial control panels, smart home dashboards, automotive diagnostics tools, and other embedded applications requiring robust connectivity, responsive graphics, and CAN/CAN FD communication.
