Arduino MKR CAN Shield is designed to enable Arduino MKR Boards to connect to a Controller Area Network (CAN) BUS. Based on the Microchip Technology MCP2515 CAN Controller with SPI Interface, the MKR CAN shield, simplifies interfacing with industrial systems and automotive applications. An on-board switch allows users to easily enable or disable the termination resistor. This MKR CAN Shield is compatible with the MKR family of Arduino boards. It uses Pin 7 to generate an interrupt when there is data coming from the CAN bus.
