Why Teensy Is One of the Best Microcontrollers for CAN Bus Applications
When engineers begin working with Controller Area Network (CAN) systems, one of the first questions is usually, "Which microcontroller should I use?" The answer depends on the application, but one platform consistently stands out for its combination of performance, flexibility, and ease of development: Teensy. Originally developed by PJRC, the Teensy family has earned an excellent [...]
Building High-Speed Data Loggers with Teensy: From CAN Bus to Connected IoT Systems
Data logging has evolved far beyond simply recording CAN messages to a memory card. Today's engineers expect real-time visualization, multi-channel data acquisition, remote connectivity, cloud integration, and support for modern protocols such as CAN FD—all while maintaining deterministic performance and low latency. If you are designing a professional-grade data logger, the choice of hardware platform can [...]
Arduino Due Dual CAN Bus Development Platform for Rapid CAN Bus and SAE J1939 Prototyping
One of the biggest obstacles in CAN bus development is not understanding the CAN protocol itself—it is finding a development platform that lets you move from an idea to a working prototype without spending weeks configuring hardware, writing low-level drivers, or debugging interface electronics. Whether you are developing an automotive controller, an industrial CAN node, an [...]
Developing SAE J1939 Applications with ARD1939 and Copperhill Technologies Hardware
One of the challenges of developing SAE J1939 applications is finding a protocol stack that is both affordable and flexible enough for prototyping, education, and custom embedded projects. To address this need, we developed ARD1939, a portable C++ SAE J1939 protocol stack that serves as the software foundation for many of our development projects and examples. Originally [...]
Raspberry Pi CAN FD and 10BASE-T1L: Building Industrial IoT and Embedded Networking Solutions
The Raspberry Pi has become one of the world’s most popular embedded computing platforms. It is inexpensive, powerful, runs a full Linux operating system, and supports countless programming languages and development tools. Yet many engineers quickly discover a limitation when they move from software development into real-world industrial applications. The Raspberry Pi provides Ethernet, USB, Wi-Fi, Bluetooth, [...]
Raspberry Pi CAN Bus and LIN Bus Interface: CAN FD Development Made Easy
The Raspberry Pi has evolved far beyond its educational roots. With modern multi-core processors, generous memory, Linux support, and an enormous software ecosystem, it has become one of the most capable embedded computing platforms available today. When combined with a CAN and LIN interface, the Raspberry Pi transforms into an excellent development platform for automotive, industrial [...]
ESP32-S3 MicroPython Programming for CAN Bus and NMEA 2000
The embedded systems world has traditionally been dominated by C and C++, but over the past several years another language has been gaining remarkable momentum: Python. More specifically, MicroPython has become one of the most attractive development environments for engineers who want to prototype and deploy embedded applications quickly without sacrificing access to the underlying [...]
CANPico V2 with Raspberry Pi Pico WH: Build Connected CAN Bus Applications with MicroPython and Wi-Fi
Have you ever wanted to build a smart system that sends data to the cloud, responds to remote commands, or monitors equipment in real time? With the CANPico V2 featuring a pre-installed Raspberry Pi Pico WH, those ideas can become working prototypes in hours instead of weeks. Combining industrial-grade CAN Bus hardware, integrated Wi-Fi, and the [...]
Building a Classical CAN to CAN FD Gateway with ESP32-S3: A Powerful Migration Platform for Next-Generation Networks
As CAN FD (Flexible Data-Rate) continues to gain adoption across automotive, industrial, agricultural, and heavy-duty vehicle applications, many developers face a common challenge: How do you connect legacy Classical CAN networks with newer CAN FD systems? One practical solution is a protocol gateway that can receive messages on one network, process or translate them, and transmit [...]
