The invention provides a gain control circuit and method, a circuit board, a vehicle-mounted electronic device, a computer storage medium and a vehicle, and the gain control circuit comprises a gain adjustment unit and a gain control unit. The gain adjustment unit is used for performing gain adjustment on the antenna radio frequency signal and outputting the antenna radio frequency signal; and the gain control unit is used for adjusting the gain adjustment unit according to the corresponding gain value output by the gain adjustment unit. According to the scheme, the gain adjustment unit is arranged to perform gain adjustment on the antenna radio frequency signal and output the signal, and whether the output corresponding gain value meets the requirement is monitored in real time, so that whether the gain adjustment unit performs adjustment according to the requirement is judged, and the output corresponding gain value meets the requirement after the adjustment of the gain adjustment unit. The gain control circuit can flexibly adjust the gain value of the radio frequency signal of the antenna, thereby avoiding the limitation of the application of the antenna, and improving the universality of the application of the antenna.
