What is a CAN Bus?

A CAN Bus (Controller Area Network Bus) is a robust vehicle bus standard designed to allow microcontrollers and devices to communicate with each other within a vehicle without a host computer. It is widely used in automotive applications for real-time data exchange between various electronic control units (ECUs). CAN Bus helps improve efficiency, reliability, and safety by enabling quick and accurate communication between system components such as the engine, brakes, and transmission.
