Description
Shield for the Arduino allows the use of serial busCAN. It is equipped with chips MCP2515 and MCP2551. It communicates via the SPI interface. It works with voltage of 5 V.
Pins
A full overview of the module can be found onthe website of the manufacturer.
Lines of the CAN bus, i.e. CANH and CANL were led out on the screw connections ARK and on the DB9 connector. The distribution of pins is visible in the figure below.
