/**

Do not change the following versions, they are used to check if the configurations in this file are compatible with
the current version of ESP_Panel_Board_Custom.h in the library. The detailed rules are as follows:
1. If the major version is not consistent, then the configurations in this file are incompatible with the library
and must be replaced with the file from the library.
1. If the minor version is not consistent, this file might be missing some new configurations, which will be set to
default values. It is recommended to replace it with the file from the library.
1. Even if the patch version is not consistent, it will not affect normal functionality.
