CAN-BUS Shield V1.2

Note

The update version is available now, please click CAN BUS Shield V2 to check.

CAN-BUS is a common industrial bus because of its long travel distance, medium communication speed and high reliability. It is commonly found on modern machine tools and as an automotive diagnostic bus. This CAN-BUS Shield adopts MCP2515 CAN Bus controller with SPI interface and MCP2551 CAN transceiver to give your Arduino/Seeeduino CAN-BUS capibility. With an OBD-II converter cable added on and the OBD-II library imported, you are ready to build an onboard diagnostic device or data logger.

The CAN-BUS shield V1.2 is the latest version with very considerable functions update. The changeable chip select pin provides an alternative pin to communication with the chip. An on board screw terminal makes it very convenient to connect CAN-H and CAN_L directly. Just like other Arduino compatible shield, we integrated the Arduino Uno headers on the shield so that you can plug the shield into Arduino Uno direatly. And as an expansion board, 2 grove port is added to the board to offer more possibility with the hundreds of Grove modules.

Alternative Choice

If your project is space limited, here is a Serial CAN-BUS module which has the full features of CAN Bus. The Serial CAN-BUS provides your Arduino or others MCU with the capability to communication to CAN Bus, such as hacking your vehicle. This Grove CAN-BUS module is controled by UART, that means if your MCU has a UART interface, this serial CAN BUS is available. Good news is that this Serial CAN BUS module needs only $14.9

What’s new in CAN BUS Shield V1.2

• Pads on the backside of PCBA

• Change terminal resistor to 120 Ohm

Note

CAN BUS Shield Work well with Arduino UNO (ATmega328), Arduino Mega (ATmega1280/2560) as well as Arduino Leonardo (ATmega32U4) and LinkIt One, if you want to use it with the others board, please contact us for more details.
