LIN (Local Interconnect Network)

LIN is a low cost, low speed, in-vehicle network intended to complement the higher performance CAN network. Vehicle systems with modest network requirements are placed on a LIN sub-network to reduce costs. The LIN sub-networks connect to the vehicle’s CAN network via gateways. LIN uses a single-wire enhanced ISO9141 implementation (non-OBDII protocol).
