Testing NMEA 0183 For The PICAN-M - NMEA 0183 & NMEA 2000 HAT For Raspberry Pi
PICAN-M - NMEA 0183 & NMEA 2000 HAT For Raspberry Pi Our PICAN-M (M = Marine) is a Raspberry Pi HAT with NMEA 0183 and NMEA 2000 connection. The NMEA 0183 (RS422) port is accessible via a 5-way screw terminal. The NMEA 2000 port is accessible via a Micro-C connector. The board comes with a 3A SMPS (Switch [...]
Embedded ARM Modules For IoT Applications Support Two CAN FD Ports
The TQMax4xxl modules by TQ Systems represent an LGA (Land Grid Array) based on the Sitara AM243x microcontroller and the AM64xx processor with up to six cores from Texas Instruments. Possible applications include servo motor controllers (for robotics), industrial gateways, data collectors, and small edge servers in production, providing data for the cloud. The module size of [...]
Wireless IoT Project Development with the ESP32
The ESP32 represents a low-cost, low-power System-on-Chip (SoC) microcontroller with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series utilizes either a Tensilica Xtensa LX6 microprocessor in dual-core and single-core variations, Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power management [...]
Advanced IoT Programming Using The Raspberry Pi 4 And Python 3
Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built-in data structures, combined with dynamic typing and dynamic binding, made it very attractive for Rapid Application Development. It is used as a scripting or glue language to connect existing components. Python's simple, easy-to-learn syntax emphasizes readability and therefore reduces the cost of [...]
SAE J1939 250k/500k Baudrate Converter Using Arduino Due With Dual CAN Bus Port
In the past months, customers have approached me regarding a CAN Bus baud rate converter for SAE J1939 networks. The original SAE J1939 Standards Collection was limited to a baud rate of 250k, basically to keep things simple and reliable. I don't know what triggered the decision to add the additional 500k baud rate. From [...]
SAE J1939 Protocol Converter Supports Modbus And Ethernet Connectivity
Axiomatic Technologies announced the release of their AX141810, a Modbus router with CAN Bus and Ethernet connectivity. It is available in two variants. The protocol converter is user-configurable via a web browser, featuring data exchange between a CAN Bus network, specifically SAE J1939, EIA-485, and Ethernet.The unit integrates one isolated extended frame format CAN Bus interface, [...]
ESP32 Project: CAN Bus, SAE J1939, NMEA2000 Converter With IoT Functionality
It was just a few weeks ago that I received some bad news. Due to the worldwide shortage of electronic components, the NXP LPC1754 processor we use for our SAE J1939 ECU Simulator with USB Port will not be available for several months, maybe even well into 2022. Consequently, it was time to rethink the design, and [...]
4G Telematics Unit With OBD-II (CAN Bus) Port For Fleet Management
The TMU Pi3 telematics unit by Autopi (Denmark) utilizes the Raspberry Pi 3 Model A+ SBC, and it connects to in-vehicle CAN Bus networks via the OBD2 port.The device uses the 1,4-GHz Broadcom BCM2837B0 SOC with Cortex-A53 64-bit quad-core processor, including 512-MiB SDRAM and a 32-GiB micro SD card with installed Raspbian Jessie operating system and Autopi [...]

Phytools announced adding a new suite of products to their portfolio of industrial networking solutions. The Teltonika Networks product line incorporates dependable, secure, and easy-to-use cellular 4G LTE mobile routers, gateways, and switches for industrial, enterprise, IoT, and M2M applications. The RUT240 is one of the most popular industrial 4G LTE WiFi routers for professional M2M and [...]
SAE J1939 vs. CAN Bus - What's the Difference?
To say it upfront, the difference between SAE J1939 and CAN Bus (Classical CAN and CAN FD) has all to do with so-called "Higher Later Protocols (HLP)," and SAE J1939 is one of them. I have written a post about HLPs (see: Guide to SAE J1939 - CAN Bus Higher Layer Protocols), but I would like [...]
