CAN-BUS Shield Category_Sensors/Contact No analog-to-digital converter (ADC) isThe 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
