What is CAN bus?
https://www.csselectronics.com/pages/...

CAN bus (ISO 11898) is a vehicle bus standard that enables robust, efficient and decentralized communication between electronic control units. It is today the de facto standard in practically all automotives (cars, trucks, tractors, buses, motorcycles, ...), maritime vessels, aerospace applications and industrial machinery.
