What is CAN bus?
https://www.csselectronics.com/pages/can-bus-simple-intro-tutorial

In this intro we explain the basics of CAN, incl. advantages, history, messages and the relation to protocols like J1939, OBD2 and CANopen!

For a quick intro to our CANedge CAN bus data loggers, check out the below!

In short, the Controller Area Network (CAN) is a standard used to allow Electronic Control Units (ECUs) to communicate in an efficient manner without a central computer.

Messages are broadcast in a system that requires very little physical wiring making CAN bus low cost, robust and efficient.

Applications of the CAN protocol include in particular automotive (cars, trucks, buses, commercial vehicles etc.), but also e.g. boats, drones and industrial automation.
