What is Controller Area Network (CAN)?

Controller Area Network (CAN) 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 primarily used in automotive applications for communication between engine management systems, transmission control, anti-lock braking, and body control systems. CAN is also used in other industries, such as industrial automation, medical equipment, and aerospace, due to its reliability and real-time capabilities.
