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

CAN-BUS Shield Different Versions Comparison

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.

1. OBD-II or CAN standard pinout can be selected by switching jumpers on the DB9 interface, the default pinout is OBD-II.
2. Added a TF card slot for data storage, and the CS pin can be either set to D4 or D5.
3. The INT pin can also be set to D2 or D3 by switching jumpers on the back of the shield.
4. 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.
5. All in one, there are more options for customization.
