Unlock the Power of Embedded Connectivity with Copperhill’s ESP32‑S3 Development Board

Meet your next go-to solution for industrial, automotive, and smart-HMI applications: a high-performance ESP32‑S3 development board featuring both Classic CAN and CAN FD, paired with a capacitive touch 480×854 IPS display. It’s purpose-built for seamless integration into modern IoT and diagnostic systems.

Engineered for Speed & Intelligence

At the core of the system is the ESP32‑S3‑WROOM‑1U‑N16R8 module, offering robust processing power via a dual-core Xtensa LX7 CPU running at up to 240 MHz. It’s equipped with 16 MB of flash memory and 8 MB of PSRAM, making it suitable for advanced graphical interfaces, real-time data processing, and AI acceleration. Wireless capabilities include Wi-Fi and Bluetooth 5 BLE, accessible through a U.FL connector for an external 2.4 GHz antenna.

Dual CAN Support: Legacy and Next-Gen

• Classical CAN (ISO 11898-1) is supported natively through the ESP32-S3’s internal TWAI controller, providing compatibility with existing CAN 2.0B networks.

• CAN FD connectivity is made possible through an onboard MCP2518FD controller, communicating over SPI and offering enhanced bandwidth and larger data payloads.

This dual-CAN design allows developers to bridge and prototype across both established and future-ready communication standards.

High-Quality Touch Display

The integrated 5-inch 480×854 IPS LCD offers vivid color, sharp contrast, and wide viewing angles. Combined with a capacitive touchscreen, it enables intuitive HMI designs and interactive controls. It's ideal for applications like vehicle dashboards, industrial terminals, and smart control panels.

Designed for Practical Integration

This board includes a thoughtful set of features to streamline development:

• Native USB support (via USB-C) for direct programming and debugging

• Wide power input range (7V to 24V DC) with onboard switching power supply and reverse polarity protection

• Boot and reset buttons, status LED, and I2C expansion connector

• External antenna support via U.FL connector (antenna not included)

These features make it a versatile choice for embedded development, whether in the lab or in field deployments.

Ideal Applications

This ESP32-S3 development board is an excellent platform for:

• Automotive diagnostics, gateway controllers, and ECU emulation

• Industrial automation and sensor aggregation systems

• HMI panels for factory floors, smart farming, or building control

• Wireless IoT nodes with high-speed CAN FD data integration

• Embedded systems that require touchscreen UIs and real-time feedback

Why Choose This Board?

Final Thoughts

For developers seeking a compact yet powerful solution that integrates display, touch input, Wi-Fi/BLE, and dual CAN communication, this ESP32‑S3 development board delivers. It’s feature-rich, rugged, and ready for your next embedded project—whether you're prototyping or deploying.

Note: External 2.4 GHz antenna is required for wireless operation and must be connected via the U.FL port.
