Sorry, but we are currently out of inventory, but please feel free to pre-order and reserve your unit(s). Expected release date is May 20th 2022.

Product Description

Leverage the power of an ARM Cortex M3 32-bit processing capability in combination with a dual CAN Bus interface to create your next CAN Bus or SAE J1939 application or prototype. By combining our dual CAN port interface, the Arduino DUE microcontroller, an OBD2 or SAE J1939 cable, and open-source software libraries you are ready to go with powerful a turn-key Arduino-based dual CAN bus solution.

Use the vast resources of Arduino software (sketches) and hardware components (shields) to create your CAN Bus, OBD2, or SAE J1939 application.

The board supports an extended input power range of 7 to 32 VDC.


  • Microcontroller board (Arduino Due) based on the Atmel SAM3X8E ARM Cortex-M3 CPU
  • 512 KB Flash Memory
  • 96 KB SRAM
  • 84 MHz Clock Speed
  • 2 CAN ports with three-pin terminal connectors
  • 3 LEDS (Power, CAN Activity Port 1, CAN Activity Port 2)
  • CAN Bus Termination resistors switchable per jumper
  • Extended power input range 7 VDC to 36 VDC
  • 54 Digital I/O Pins (of which 12 provide PWM output)
  • 12 Analog Input Pins
  • 2 Analog Output Pins

We reserve the right to use Arduino Due “clones” in case of supply shortage for the original board. We use only one other brand (OSOYOO), which we have tested thoroughly before release.

Please be aware that the Arduino Due is specified for an operational temperature range of 0 to 50C - 32 to 122F.

If you are using our product as a DEF Sensor Simulator, please read our post:

Alternate Version

Due to global shortage of electronic components, we may ship a different-looking DC/DC converter.

JCOM.CAN.DUE Alternative DC DC Converter 

Be assured, the functionality remains the same!

Possible applications include:

  • CAN to USB Gateway and Protocol Converter
  • CAN to Wireless (WiFi, Bluetooth) Gateway
  • SAE J1939 Gateway and Protocol Converter
  • CAN Data Logger
  • CAN Bridge (connecting 2 CAN networks, even at different baud rates)
  • CAN Analyzer (in combination with a suitable Windows program)
  • SAE J1939 Data Monitoring
  • CAN Bus ECU Prototyping
  • SAE J1939 ECU Prototyping

Programming Arduino - Getting Started With Sketches
by Simon Monk

Programming Arduino - Getting Started With SketchesClear, easy-to-follow examples show you how to program Arduino with ease! "Programming Arduino: Getting Started with Sketches" helps you understand the software side of Arduino and explains how to write well-crafted Sketches (the name given to Arduino programs) using the C language of Arduino. This practical guide offers an unintimidating, concise approach for non-programmers that will get you up and running right away.

Programming Arduino: Getting Started with Sketches explains basic concepts and syntax of C with simple language and clear examples designed for absolute beginners - no prior knowledge of programming is required. It leads you from basic through to advanced C programming concepts and features dozens of specific examples that illustrate concepts and can be used as-is or modified to suit your purposes.

  • All code from the book is available for download.
  • Helps you develop working Sketches quickly.

Coverage includes: C Language Basics; Functions; Arrays, Strings; Input / Output; Standard Library Goodies; Storage; LCD Displays; Programming for the Web; Program Design; C++ and Library Writing
