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 [...]
Why Would You Need Two CAN Ports on a Raspberry Pi?
When developers first start working with CAN bus networks, a single CAN interface is usually sufficient. It allows them to monitor traffic, transmit messages, and develop applications for automotive, industrial, marine, or agricultural systems. However, as projects become more sophisticated, the limitations of a single CAN port quickly become apparent. This is where dual-channel CAN interfaces [...]
When CAN FD Meets Precision Positioning: Building Next-Generation Vehicle Telematics with Raspberry Pi
Modern vehicles generate enormous amounts of data. Engine parameters, fuel consumption, battery status, vehicle speed, GPS location, driver behavior, and diagnostic information all play a role in today’s connected transportation systems. The challenge is not collecting the data—it is collecting the right data reliably, even when GPS signals disappear. That is where the PiCAN FD with GPS/GNSS [...]
CAN Bus Troubleshooting with the PiCAN HATs: Why the Board Is Probably Not the Problem
The PiCAN product line has become the go-to CAN Bus interface solution for Raspberry Pi developers, system integrators, educators, and industrial engineers worldwide. From entry-level CAN Bus connectivity to advanced dual-channel CAN, CAN FD, GPS/GNSS integration, RS232, RS485, and real-time industrial networking, PiCAN boards combine robust hardware design with seamless Raspberry Pi integration. Whether you [...]
CAN Bus Repeater Explained: How the CAN-11 Solves Ground Loops, Noise, and Network Expansion Problems
When engineers first learn about CAN bus networks, the concept appears deceptively simple: connect all nodes to the same two wires, add termination resistors at both ends, and communication just works. In small systems, that is often true. However, as soon as a CAN network grows beyond a handful of devices, spans long distances, operates in electrically [...]
CANCrocodile Contactless CAN Bus Reader – Access CAN Data Without Cutting Wires
Modern vehicles, construction equipment, agricultural machinery, marine systems, and industrial equipment all rely on Controller Area Network (CAN) technology to exchange critical operational data. Whether you are developing a telematics system, logging vehicle performance, troubleshooting equipment, or monitoring fleet operations, one challenge appears again and again: How do you access CAN bus data without modifying the [...]
J1939 Monitor Software and J1939 Gateways: The Complete Solution for SAE J1939 Development, Testing, and Diagnostics
Developing, testing, and troubleshooting SAE J1939 applications can be challenging, especially when engineers must deal with complex protocol details, limited vehicle access, and the need to simulate realistic network traffic. In this article, we will explore how the combination of the JCOM1939 Monitor software and the JCOM.J1939 gateway series helps solve these challenges by providing [...]
NMEA 2000 Data Gateway Applications: What You Can Build with USB and Bluetooth Access
Modern boats generate an enormous amount of information. Engine controllers report RPM, temperatures, fuel consumption, and operating hours. GPS receivers provide position, speed, and heading. Sensors monitor tank levels, battery status, wind conditions, water depth, and much more. All of this information travels across the vessel’s NMEA 2000 network. For years, accessing that data meant purchasing expensive [...]
Why CAN Bus Is One of the Most Reliable Communication Systems Ever Created
When engineers design communication systems for vehicles, industrial machinery, agricultural equipment, marine electronics, and embedded control systems, reliability is often more important than raw speed. A lost message in a music streaming application may go unnoticed. A lost message containing engine speed, brake status, steering angle, or hydraulic pressure can lead to equipment malfunction, downtime, or [...]
Why the Teensy 4.1 Triple CAN-Bus Board with Ethernet Makes an Excellent CAN Data Logger
Modern vehicles, industrial machines, marine systems, and agricultural equipment generate enormous amounts of CAN bus traffic. Capturing, storing, and analyzing this data is essential for diagnostics, performance monitoring, predictive maintenance, fleet management, and product development. While there are many commercial CAN data loggers available, they often suffer from one or more limitations: High cost Limited customization Proprietary software Restricted storage [...]
