The circuit CAN stands for \"Controller Area Network\".
CAN bus is a serial communication protocol, widely used in automotive electronics and industrial control fields.
It has the advantages of fast communication speed, high reliability and strong anti-interference ability, and is widely used in real-time control system.
Should be called CAN network, is a number of microcontroller as the core of the electronic module, through the CAN bus protocol to transmit, exchange information - and then reduce the drawbacks of hard wire to transmit signals, can reduce the weight of the harness, and increase intelligent functions.
