Availability date:
CAN bus Grove module is an isolated transceiver for Controller Area Network (CAN) which can be used to build a complex CAN communication network as used car control network, industrial field control or security system.
The module have a built-in DC-DC isolated power chip to avoids noise / interference injection into the main's power supply (which may damage sensitive circuits in the project).
The isolated CAN transceiver is based on the CA-IS3050G chip supporting differential reception / transmission. The CAN bus can have up to 110 nodes with a theoritical transmission rate reaching 1Mbps. The module also have current limiting, over-voltage, grounding loss protection (–40 V to 40 V) plus a thermal shutdown function. Such protections can prevent output short-circuit issue and meets the ISO11898-2 specifications.
CAN is an International ISO standard for serial communication protocol. CAN is also a 2 wire bus topology where several devices share the same bus. Any device can try to get the control over the bus at any time (there is no bus master but a notion of "priority"). CAN is a kind of serial communication network which can effectively support distributed control or real-time control.
The distributed control system based on CAN bus adopts multi master competitive bus structure, which has the characteristics of multi master station operation, decentralized arbitration and broadcast communication.
CAN have several advantages:
