Raspberry Pi Pico CAN Bus System with Micro-Python Installed
The Raspberry Pi PicoBoard is an inexpensive and versatile development board designed for the RP2040 microcontroller chip developed by Raspberry Pi. It features an RP2040 microcontroller chip with 2MB of Flash, and a micro-USB port for power, data, and programming. The 40-pin dip-style header provides 26 multi-function 3.3V GPIO, 23 digital-only GPIO, and three ADC-compatible [...]
SAE J1939 Functional Safety Communications Protocol
Commercial road and off-highway vehicles, as well as off-road construction machines, frequently utilize J1939-based application layers. In response to the growing need for functional safety, SAE has created specific protocols for CAN CC (classic) and CAN FD: J1939-76 and J1939-77, respectively. An article on the CiA (CAN-in-Automation) website discusses the SAE standards for functionally safe communications on CAN [...]
Industrial Grade CAN/CAN FD Bus Data Analyzer with USB Port
The USB-CAN-FD adapter is a versatile tool that empowers engineers with its industrial-grade high-performance capabilities. It serves as a USB to-CAN FD adapter, CAN/CAN-FD bus communication interface card, and CAN/CAN-FD protocol data analyzer.

NMEA 2000 Product Certification for Marine Applications
The NMEA 2000 product certification is a mark of reliability, ensuring quality and interoperability for NMEA 2000 networks. It guarantees that a device supports a mandatory set of protocol services and hardware requirements. Developers can carry out the certification themselves or be supported by engineers with experience in NMEA 2000 certification. NMEA 2000 is a protocol [...]
CANFDuino: Upgrading the Hardware to 24 VDC Power Supply
Today, we are addressing a frequently asked question since the product's launch: 'Is it possible to power CANFDuino off of 12 or 24 V power?'. Our previous response, 'Yes, using the prototyping space to add a regulator', while accurate, may not have been as helpful as we intended. To provide a more practical solution, we [...]
Arduino-Compatible Open-Source Dual CAN-FD Network Analyzer
In a previous post, we highlighted SavvyCAN, developed by Collin Kidder, as the most effective open-source software for CAN bus sniffing. We have also worked on enhancing the compatibility of the CANFDuino and the GVRET protocol with SavvyCAN to support CANFD messages from two ports. With these updates on GitHub, you can now sniff two CANFD busses with [...]

The Myth: Controller Area Network is “Too Easy to Hack”
The potential security issues of CAN and its higher-layer protocols attract increased attention from the automotive, control, and medical industries. At first glance, believing that a well-documented standard like ISO 11898 makes it easier to manipulate control functions, whether in an automobile or a medical device such as an MRI or CT scanner, makes sense. [...]
ESP32 Processor with Internal SJA 1000 CAN Bus Controller
This post is an excerpt from our application note Controller Area Network (CAN) Development with ESP32. The ESP32 is a low-cost, low-power system-on-chip microcontroller with integrated WiFi and dual-mode Bluetooth. It employs a Tensilica Xtensa LX6 microprocessor in dual-core and single-core variations. It includes built-in antenna switches, RF balun, power amplifiers, low-noise receive amplifiers, filters, and power [...]
