SparkFun CAN-BUS Shield

The CAN-BUS Shield provides your Arduino or Redboard with CAN-BUS capabilities and allows you to hack your vehicle. This shield allows you to poll the ECU for information including coolant temperature, throttle position, vehicle speed, and engine rpms. You can also store this data or output it to a screen to make an in-dash project.

It uses the Microchip MCP2515 CAN controller with the MCP2551 CAN transceiver. CAN connection is via a standard 9-way sub-D for use with OBD-II cable. Ideal for automotive CAN application. The shield also has a uSD card holder, serial LCD connector and connector for an EM506 GPS module. These features make this shield ideal for data logging application.

Note

A DB9 Cable is not included with this shield. You can buy one here.
