1. A circuit board, comprising:
a board body;
a main circuit, located on the board body; and
a standby circuit, located on the board body, and electrically connected to the main circuit, the standby circuit comprising:
a first pressure detection circuit, located at an area being monitored of the board body; and
a control circuit, outputting a first signal or a second signal according to a first detection value and a first predetermined range of the first pressure detection circuit;
wherein the main circuit comprises a main power transmission circuit and an operating circuit; the control circuit outputs the first signal when the first detection value falls within the first predetermined range; and the control circuit outputs the second signal when the first detection value does not fall within the first predetermined range, and the main power transmission circuit stops outputting power to the operating circuit when receiving the second signal.
