The ELE CAN-Bus Shield V1.5 adds CAN-Bus communication capability to your Arduino. Built around the Microchip MCP2515 CAN controller and MCP2551 CAN transceiver, it supports CAN V2.0B at speeds up to 1 Mb/s with both standard (11-bit) and extended (29-bit) frames.

The shield connects via a standard 9-pin sub-D connector, making it ideal for OBD-II automotive diagnostics. An onboard microSD card holder allows direct data logging without additional hardware.
