Controller Area Network

**Controller Area Network**

A Controller Area Network (CAN) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other without a host computer. Primarily used in automotive applications, CAN enables efficient and reliable communication between various electronic control units (ECUs) within a vehicle. This protocol supports real-time data exchange and is known for its high fault tolerance, error detection, and multi-master capabilities. Beyond automotive uses, CAN networks are increasingly employed in industrial automation, medical equipment, and other embedded systems where dependable communication is critical.
