Dual CAN Bus Interface For Arduino Due With Extended Power Range

The jCOM.CAN.DUE-X, a dual CAN bus interface for the Arduino Due, is not an Arduino shield in the common sense. The board incorporates dual CAN transceivers required by the two integrated CAN ports on the Arduino Due while allowing the operation with any Arduino-compatible shield that supports the necessary 3.3 VDC power requirements.
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. Leverage the 32-bit processing capability of the Arduino DUE plus the built-in CAN ports for your next prototype.
In order to more efficiently serve automotive and industrial applications, the jCOM.CAN.DUE-X board supports an extended input power range of 7 to 36 VDC to power the entire system, i.e. including the Arduino Due itself.
Possible applications include

• CAN to USB Gateway and Protocol Converter
• 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 ECU Prototyping
• SAE J1939 ECU Prototyping

Features

• 2 CAN ports with three-pin terminal connectors
