In some embodiments, the multifunction interface further comprises a communication component when identified by way of the electrical signal; when the multifunctional interface is connected with the current functional device, the main control board is in communication connection with the functional device through the communication assembly so as to identify the currently connected functional device.
In some embodiments, the communication connection may be a wired connection communication.
In some embodiments, the communication connection may be a wireless connection communication, such as a short-range wireless communication mode, e.g., RF, bluetooth, etc.
