ESP32S3 Board with CAN FD and Classical CAN Ports

This development board is built around the ESP32-S3-WROOM-1-N8R8 module, offering a powerful combination of wireless connectivity, advanced processing capabilities, and robust CAN communication. The ESP32-S3 integrates Wi-Fi, Bluetooth 5 (including LE and mesh), and includes native support for Classical CAN. For modern automotive and industrial networking needs, CAN FD is supported via the external MCP2518FD controller, making the board suitable for both legacy and next-gen CAN-based applications.

Unlike many ESP32 boards that rely on a separate USB-to-UART bridge, this board features native (True) USB support via the ESP32-S3’s integrated USB OTG interface. This enables direct USB connectivity for programming, debugging, and serial communication without the need for an external USB-UART chip.
