Abstract

Electronic equipment includes: a first substrate; a second substrate; and a harness that connects the first substrate and the second substrate with other. The first substrate includes: a conversion unit that outputs converted power converted from supply of power supplied by a power source, and a control unit that outputs a control signal used to control output of the supply of power to the second substrate. The second substrate includes: a semiconductor circuit operated by the supply of power and the converted power, and a connector that outputs the control signal to the power source. The harness includes a signal line of the control signal and a power line through which the converted power is supplied from the first substrate to the second substrate.

Claims
