Abstract: The present invention relates to a baseboard testing interface, which comprises: a baseboard, on which a plurality of first electronic components, a plurality of signal lines, and a first connection interface are configured, and the first electronic components are coupled to the signal lines; a slot disposed on the baseboard for an external interface adapter to plug in; and a debugging adapter that is plugged into the slot, and a plurality of second electronic components and a second connection interface are configured thereon; when the debugging adapter is plugged into the slot and fixed on the baseboard, the second connection interface is contacted with the first connection interface, such that the signals can be transmitted between the baseboard and the debugging adapter. In addition, the present invention further provides a baseboard testing method.

Abstract: A battery having a universal serial bus (USB) connector is provided. The battery includes a battery control circuit, a voltage regulator circuit, a USB connector, and a device connector. The battery control circuit is used for providing a power source. The voltage regulator circuit is coupled to the battery control circuit, and used for regulating the voltage of the power source. The USB connector is coupled to the battery control circuit, and used for being connected with an external USB device and providing the power for the USB device. The device connector is coupled to the battery control circuit, used for being connected with a portable electronic device and providing the power for the portable electronic device. Therefore, the cost for purchasing subsidiary battery can be saved by using the battery of the present invention. The idea of implementing one battery with multipurpose also fits with economical benefit.
