CAN (Controller Area Network)

A Controller Area Network (CAN bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other in applications without a host computer.

It is a message-based protocol, designed originally for multiplex electrical wiring within automobiles to save on copper, but is also used in many other contexts.

  • Passenger vehicles, trucks, buses (gasoline vehicles and electric vehicles)
  • Electronic equipment for aviation and navigation
  • Industrial automation and mechanical control
  • Elevators, escalators
