Description
Hacking vehicles becomes easy with CAN BUS and Arduino! CAN-BUS Shield which adopts MCP2515 CAN-BUS controller with SPI interface and MCP2551 CAN transceiver to give you Arduino/Seeeduino CAN-BUS capability. With the help of CAN-BUS Shield, you can use easily interact with your car by using Arduino boards.
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.
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.

What is CAN?
- CAN which stands for Controller Area Network is used to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer which allows for control and data acquisition. These devices are also called Electronic Control Units (ECU) and they enable communication between all parts of a vehicle.
- CAN is a serial communication bus designed for industrial and automotive applications. For example, they are found in vehicles, farming equipment, industrial environments, etc
Previously we have made two versions of CAN-BUS Shield, 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 much valuable advice (Thanks to all the users who replied to us), so we decided to make an update and here it is - CAN-BUS Shield V2.
CAN-BUS Shield Different Versions Comparision
The CAN-BUS Shield V2 still uses MCP2515 as CAN-BUS controller and MCP2551 as CAN transceiver. There are really many updates compare with the precisions.
- OBD-II or CAN standard pinout can be selected by switching jumpers on the DB9 interface, the default pinout is OBD-II.
- Added 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.
- We moved the P1 pad from front to the back of the shield to make it easier to cut and solder in case you want to use more than 2 CAN-BUS Shields, it is needed to cut the P1 pad.
- All in one, there are more options for customization.
