CAN Controller Area Network is an abbreviation, is the ISO international standardization of serial communication protocol. CAN's performance and reliability has been recognized, and is widely used in industrial automation, marine, medical equipment, industrial equipment and other aspects.
Compared with the traditional 485 bus, CAN bus has many advantages. The Arduino CAN Shield as using MCP2515 CAN controller, TJA1050 CAN transceiver as (similar to 485 in the MAX485 transceiver chip), and provide detailed information and reference library Arduino platform, can be installed directly on the Arduino platform CAN communication between the plates, for those who want self-CAN bus students or engineers, is a good choice.
