CAN BUS Shield Arduino Uno in Hallroad Lahore

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, such as an automotive diagnostic bus.

  • Implements CAN V2.0B at up to 1 Mb/s
  • SPI Interface up to 10 MHz
  • Arduino/Seeeduino Completely compatible
  • Standard (11 bit) and extended (29 bit) data and remote frames
  • Industrial standard 9 pin sub-D connector
  • Two receive buffers with prioritized message storage
  • Operating voltage: DC5-12V
  • Size: 78mmx53.5m
  • Applications:
  • Industrial control
  • Car control field.
What’s new in CAN BUS Shield V2.0


  • OBD-II or CAN standard pinout can be selected by switching jumpers on DB9 interface, the default pinout is OBD-II.
  • Add a TF card slot for data storage and the CS pin can be either set to D4 or D5.
  • The INT pin can be set to D2 or D3 by cutting and soldering pad on the back of the shield.
  • Moved the P1 pad from front to the back of the shield to make it easier to cut and solder.
  • 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.


  • Add the function and example to access the data of your car.
  • Add the function to read the SD card.
  • Add the example to store the data of your car into the SD card.
  • Fix some bugs and optimize some program.
