A communication module and a terminal include a new-generation mini-peripheral component interconnect express (PCIe) interface, a power switch, a charging unit, a delay unit and an ON/OFF control unit. The charging unit, the power switch, the delay unit and the ON/OFF control unit are separately connected to the new-generation mini-PCIe interface. The power switch is connected to the charging unit, and the charging unit is connected to a power source end of the communication module. A universal serial bus (USB) data pin is shorter than a power source pin. Thereby, the communication module and the terminal have stability and reliability.
