Abstract
A Type-C insertion direction detection circuit, a circuit board, and an electronic device are disclosed. The detection circuit may include: a switch module, having an input end configured to be connected to a VBUS end of the Type-C socket, the input end of the switch module is connected to a first CC end and/or a second CC end of the Type-C socket, and the switch module is configured to change an on/off status according to a first level received at the input end from the first CC end and/or the second CC end, and output a second level at a drive end of the switch module, for the electronic device to determine a plugging relationship between a Type-C plug and the Type-C socket according to the second level.
