And once the mould is opened, the functions need to be added and changed at the later stage, so that the cost is very high, and some of the moulds can not be modified. The integration of various communication interfaces and communication protocols consumes a large amount of software and hardware resources, so that the cost of the software and the hardware is greatly increased.
