CAN-BUS Shield V2 adopts MCP2515 and MCP2551 for controller and transceiver, it is compatible with Arduino which means it can switch an Arduino board like Arduino Uno to start your CAN-BUS project.

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. Thanks for CAN-BUS, makers are able to hack their cars more conveniently. In order to make it more convenient to interact with cars, we released the CAN-BUS Shield which adopts MCP2515 CAN-BUS controller with SPI interface and MCP2551 CAN transceiver to give you Arduino/Seeeduino CAN-BUS capability.
Previously we have made two versions of CAN-BUS Shield, the V1.0 and V1.2. They are all awesome shields that widely liked by our users. In order to make it better, several months ago we conducted a survey about CAN-BUS Shield V1.2 and received many valuable advices (Thanks to all the users who replied to us), so we decided to make an update and here it is - CAN-BUS Shield V2.
The CAN-BUS Shield V2 still uses MCP2515 as CAN-BUS controller and MCP2551 as CAN transceiver. Despite of that, there are really many updates. First and most importantly, OBD-II or CAN standard pinout can be selected by switching jumpers on DB9 interface, the default pinout is OBD-II. Secondly we add a TF card slot for data storage and the CS pin can be either set to D4 or D5. The INT pin can also be set to D2 or D3 by switching jumpers on the back of the shield. If you want to use more than 2 CAN-BUS Shield, it is needed to cut P1 pad. In V2, we moved the P1 pad from front to the back of the shield to make it easier to cut and solder. All in one, there are more options for customization.
Consider that the D0/D1 pin are usually used for downloading code, we changed the serial Grove connector to pin A0/A1. The I2C grove connector is also changed to more reasonable standard SDA/SCL pin instead of previous A4/A5. The two grove connectors are both changed to horizontal rather than vertical to the shield so that it would be more convenient when connecting to other grove modules.
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
If you want to record the GPS log at the same time, this OBD-II CAN Bus GPS Development Kit is recommended. The board can be plugged directly into the car via ODB-II interface and supports arduino programming.
Implements CAN V2.0B at up to 1 Mb/s
Industrial standard 9 pin sub-D connector
OBD-II and CAN standard pinout selectable.
Changeable chip select pin
Changeable CS pin for TF card slot
Changeable INT pin
Screw terminal that easily to connect CAN_H and CAN_L

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.
If you want a CAN Bus function for others mcu, please try Serial CAN-BUS module.
In this video, I am connecting to the Renault Megane 3 vehicle with the Arduino Uno + SeeedStudio CAN Bus Shield V2 to analyze the data / messages passing through the vehicle's CAN bus (sniffing). If you use CAN Bus Protocol in your vehicles, you can listen to your vehicle with the same actions.
Ever wanted to play a car/truck simulator with a real dashboard on your PC? Me too! I'm trying to control a VW Polo 6R dashboard via CAN Bus with an Arduino Uno and a Seeed CAN Bus Shield. Inspired by Silas Parker.

Hi,there~ Sure you can, the V2 and V1.2 share the same library. Regards
Hi Bryan ~ Is your Canbus shield V1.0 or V1.1 or V1.2.If yours is V1.0 ,please change the SPI_CN PIN to D10. You can find the way in our wiki # http://wiki.seeed.cc/CAN-BUS_Shield_V2.0/ #.If yours is V1.1 or 1.2, please tell us more detail,you can contact our email # email@example.com #. The V1.1 and V1.2 is compatible with V2,so there sould be some setteing error.Regards
Hi Cory~ According to our experience, the voltage of the SD card is 3.3V, there is no damage IO or SD card situation. So in order to reduce costs, we do not add IO protection circuit.Regards
<p>Hello,</p><p>YES! It support J1939<br></p>
Hi there, CAN BUS Shield Work well with Arduino UNO (ATmega328), Arduino Mega (ATmega1280/2560) as well as Arduino Leonardo (ATmega32U4). It uses the SPI for the communication, it shall work with due, but we do not test it yet. thanks.
Hello, the wiki will be available before Aug 15, as well as the schematics. Thanks.
Hello Michael, CAN-Bus Shield is designed for Arduino and its compatible boards, while Serial CAN-Bus is control by UART, in theory, it work with any platform that with UART.
What is the Green interface? All I have is the can bus shield and an arduino
