Detailed explanation of the topology of the LIN bus

The topology of the LIN bus is a single-wire bus, which applies the concept of a single host and multiple slaves. The bus voltage is 12V, and the maximum transmission rate is 20kbps. Due to physical layer limitations, a LIN network can connect up to 16 nodes, and typical applications are generally less than 12 nodes. There is only one host node and 1 to 15 slave nodes. This structural design makes the LIN bus widely used in automotive electronic systems.
