Description
technical field [0001] The invention relates to the field of automatic control equipment, in particular to a multipurpose main board unit with electromagnetic protection and encryption functions. Background technique [0002] In recent years, with the development of new technologies such as communication, measurement and control, and embedded technology, in order to meet various needs, designers need to design different terminals. No matter how these terminal designs change, the core parts such as processors and memories are different. Changes, the current design of the terminal is to use the existing processors and memories on the market as design components, resulting in a large number of repeated designs, prolonging the development cycle, and making the production process relatively complicated, which is not conducive to assembly . [0003] At the same time, since the terminal may be deployed in a complex industrial environment, it is also necessary to provide electromag...
