Please consider! The DEF Sensor Simulator is not an off-the-shelf device. It was originally created by a team of automotive engineers as a proof-of-concept solution for bypassing malfunctioning DEF sensors. The project consists of a parts list and open-source control code, and anyone using it must assemble and program the…

In the heavy-vehicle, mobile-machinery and industrial equipment world, the CAN bus remains a workhorse for on-board networks. But merely having physical CAN isn’t enough: what enables rich diagnostics, telematics and fleet data is the higher-layer protocol stack such as SAE J1939. The Teensy 4.1 Triple CAN Bus Board with Ethernet…
If you’re looking to dive deep into the world of medium- and heavy-duty trucks—whether as a technician, a fleet maintenance manager, or a student of transportation technologies—this book is a standout resource. Heavy Duty Truck Systems offers one of the most comprehensive and up-to-date overviews of heavy vehicle systems I’ve…
Maintaining and troubleshooting heavy-duty trucks requires tools that go far beyond a basic automotive OBD-II reader. Whether you work with Freightliner, International, Paccar, Detroit Diesel, or Cummins engines, you need a scanner built specifically for the rugged and complex systems inside Class-4 through Class-8 diesel vehicles. The ANCEL HD601 J1939…
If you’re working with a Cummins heavy-duty engine, you already know the power and reliability these machines deliver. But to keep them performing at their best — and avoid costly downtime — you need effective diagnostics tools. Enter the INLINE Adapter for Cummins Data Link / Engine Diagnostic (ASIN B0FNMFTQ1D):…
A recent internal market study by Copperhill Technologies uncovered a surprising but critical shortcoming across all commercially available SAE J1939 baud rate converters: none of them explicitly address the issue of Silent or Listen-Only Mode. This omission, whether in marketing descriptions or technical documentation, can have significant implications for system…
Rail is in the midst of a big energy storage shift: away from lead-acid batteries and toward lithium-ion. The reasons are persuasive: lithium-ion offers higher energy density, longer life, and lower maintenance. But switching is more than dropping in new batteries. It demands visibility, safety, and diagnostics under the harsh…
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…
Looking to take your CAN-bus and SAE J1939 projects to the next level? Whether you’re building a data logger, protocol converter, or a full-blown J1939 ECU prototype, the Arduino-Due-Based SAE J1939 Programming Kit makes it easier than ever. Here’s why this all-in-one kit deserves a spot in your toolkit. The…
The SAE J1939 250 k / 500 k Baud Rate Converter by Copperhill Technologies was never intended to be a mainstream product. Its origin is rooted in a simple customer request—an engineer approached us looking for a device that could allow a 250 k J1939 network to communicate seamlessly with…
