In this embodiment, the main controller 10 may be selected as an FU6832S processor, wherein the main controller 10 has a package structure as shown in fig. 2, and it should be noted that, in the present invention, pins of different components are denoted by the same reference numerals to indicate that the different components have corresponding connection relationships.
