In automobiles, the LIN (Local Interconnect Network) is a low-priced serial communication system that was developed specifically for simple electronic assemblies to be cross-linked.

It is particularly useful in areas where sensors and actuators are simple enough to be networked but efficiency is not required. The sub-system for example doors, seats, steering wheels are generally connected with LIN (Local Interconnect Network) are also connected to CAN-based networks such as body, chassis. Simple access is provided with CAN-based diagnostic and service tools.

The communication principle for KIN technology is a serial single-wire communication protocol that is based on the SCI interface standard i.e. (UART). The LIN bus is controlled by the master with a maximum latency time.

LIN got a special characteristic where slave devices are synchronized via the bus with low-priced nodes to be implemented with simple resonant circuits. The communication of data takes place with a 12 V single wire and 20 Kbit/s as the maximum data transmission rate.

A typical LIN system is designed for up to 16 nodes due to only 64 identifiers and with a relatively low bit rate.

The low cost of the LIN system is contributed because of the synchronization of the clock, simple UART communication, and the single wire medium.
