An isolated CAN_BUS shield up to 1000V designed in Italy by the RubinoLab team composed by Guido and Luigi Rubino, two brothers (Ph.D. Electronic Engineering).

Excellent for use in industrial environments (with standard CAN-out pin-out on DB-9), in automotive or car diagnostics, and for new projects such as those in the industry 4.0 internet of things.
Features
- Fully compliant with the CAN 2.0A & CAN 2.0B Bosch specifications
- ISO 11898-2 (High speed CAN) physical interface
- CAN baud rate adjustable by software up to 1Mbps
- 1000Vrms galvanic isolation barrier
- Bus-Fault Protection of –27 V to 40 V
- ESD protection
- Common Mode Filters CAN
- 120 ohm terminating resistor at CAN node (setup)
- Isolated power supplies between board Arduino and CAN-BUS (the device prevents noise currents on a data bus or other circuits from entering the local ground and interfering with or damaging sensitive circuitry)
- Fully compatible with higher level protocols such as CANopen, DeviceNet, NMEA2000, ARINC825, ISO11783, CAN Kingdom, CANaerospace
- Industrial standard DB-9 connector (possibility to supply external to 12V dc)
- Protection inversion of polarity on the DB-9 (supply external to 12V dc)
- LED indicators
Applications
- Industrial Automation, Control, Sensors, and Drive Systems
- Industria 4.0 internet of things
- Building and Climate Control (HVAC) Automation
- Security Systems
- Transportation
- Medical
- Telecom
- CAN Bus Standards such as CANopen, DeviceNet, NMEA2000, ARINC825, ISO11783, CAN Kingdom, CANaerospace
