The Teensy 4.1 Triple CAN-Bus Board with Ethernet is a new product from Copperhill Technologies, expanding our lineup of CAN bus and IoT development tools. Designed to meet the growing demand for bridging traditional embedded networks with modern IoT solutions, it provides engineers and developers with a powerful, reliable, and easy-to-use platform for prototyping and deployment.
Connecting Embedded Networks with IoT
The rapid evolution of connected technologies has made it increasingly important to find ways of linking traditional embedded networks with modern IoT infrastructure. One of the most powerful solutions to this challenge is the integration of CAN Bus, the backbone of automotive and industrial communication, with Ethernet-based IoT systems. The Teensy 4.1 Triple CAN-Bus Board with Ethernet is designed precisely for this purpose, offering engineers, developers, and researchers a compact yet powerful platform for creating gateways, controllers, and data acquisition systems that seamlessly span both domains.
High-Performance Core with Teensy 4.1
At its core, this board is powered by the Teensy 4.1 microcontroller, which delivers exceptional processing performance with its 600 MHz ARM Cortex-M7 processor. Installed on the board is a robust set of communication features: two classical CAN 2.0B interfaces, one CAN FD interface, and a built-in Ethernet connector. This combination provides a direct path for translating messages between in-vehicle or industrial CAN networks and Ethernet-based cloud or local IoT services. Developers can create systems where vehicle telemetry, machine control data, or sensor readings can be streamed in real time to dashboards, monitoring systems, or cloud platforms for analysis and storage.
Rugged Design and Versatile Connectivity
The board is designed to be rugged and versatile. Power input is supported across a wide range, from 7 to 24 volts DC, with an onboard SMPS regulator ensuring efficient operation and reverse voltage protection for additional safety. Each CAN connection is fitted with proper termination to maintain signal integrity, while the Ethernet MagJack connector ensures stable network connections. The inclusion of an I²C header further expands its capabilities, allowing developers to integrate additional sensors or small displays directly into their applications.
Arduino IDE and Teensyduino Support
One of the greatest advantages of this platform is its compatibility with the Arduino IDE through the Teensyduino add-on. This makes the development process straightforward, enabling engineers to quickly build prototypes, test algorithms, and deploy working systems. The Arduino ecosystem provides an enormous library of code resources, from CAN drivers to Ethernet communication stacks, making it easier to connect the dots between CAN data and IoT applications. Beginners can leverage these tools for fast prototyping, while professionals retain the flexibility to implement advanced C/C++ solutions for production-ready systems.
Wide-Ranging Applications Across Industries
The practical applications for this board are vast. In the automotive field, it can serve as a powerful J1939 or OBD-II data logger that collects information from vehicle networks and relays it to cloud platforms for fleet management or predictive maintenance. In industrial automation, it can function as a gateway that unifies CANopen or custom CAN-based machinery with supervisory IoT platforms. Marine electronics developers can use the CAN FD and Ethernet combination to integrate NMEA 2000 data into navigation or monitoring systems. Beyond transportation and industry, the board is also well-suited for research and education, providing a platform to study the intersection of embedded networking and modern IoT practices.
Bridging CAN Bus with IoT for Future Innovation
By combining the reliability and determinism of CAN Bus with the scalability and connectivity of Ethernet and IoT, the Teensy 4.1 Triple CAN-Bus Board with Ethernet opens the door to new innovations. Whether the goal is to monitor vehicle fleets in real time, connect industrial machinery to smart dashboards, or simply experiment with advanced communication technologies, this board provides a solid foundation for creating solutions that bridge the gap between legacy networks and the connected world of tomorrow.
