The present invention discloses a circuit board group for electrically coupling electronic devices, which comprises a primary circuit board divided into an electronic device connecting section and a circuit section. The electronic device connecting section comprises a first connection port for connecting electronic devices and the circuit section comprises a second connection port. The primary circuit board is electrically connected to a secondary circuit board. A third connection port correspondingly coupled to the second connection port is disposed on the secondary circuit board at a position corresponding to the circuit section, and a through hole disposed on the secondary circuit board at a position corresponding to the electronic device connecting section for receiving the first connection port. Further, a fourth connection port is disposed on the other side of the secondary circuit board for increasing the number of installable electronic devices.
