Wherein, N is an integer greater than or equal to 2.

[0029] Here, the meaning of the two groups of burning pins symmetric about the reference jack center is that the N burning jacks in one group of burning pins are symmetric about the same reference jack center as the N burning jacks in the other group of burning pins. For example, the N burning jacks are the first jack A1 to the Nth jack AN, respectively used for transmission of different signals.

It can be understood that in other embodiments, due to different master control chips, the burning interface and pin configuration are also different. In practical application, the specific burning pin and its interface need to be determined according to the model and data manual of the master control chip.

[0030] Specifically, one end of the burning pin is connected to the master control chip through the burning jack, and the other end is connected to the burner through the burning pin. By expanding the burning pin of the burning interface 100 into two groups of burning pins arranged in a single row and symmetric about the reference jack center, and connecting the burning jacks with the same transmission signal to each other, the program burning can be realized without judging the direction of the burning pin inserted into the burning interface when the master control chip is burning.
