The invention discloses a universal circuit board test system, which comprises a test machine table and test software, wherein the test machine table comprises automatic test resources and a matrix switch, the automatic test resources are integrated together through a bus and are connected with the matrix switch and a PC (personnel computer) through interfaces, the PC is configured with the test software, the test software outputs a power supply or a signal meeting the requirements through controlling the automatic test resources via the bus, an output signal of a tested circuit board is read, meanwhile, the matrix switch is controlled through the bus so that the corresponding lead pin type in a socket is matched with the lead pin of the tested circuit board, in the work process, the interface definition of the circuit board is added into a test software database, the system automatically switches each lead pin function of the socket for outputting the signal or the power supply conforming to the requirements, in addition, the output interface of the circuit board is automatically connected onto corresponding equipment of the automatic test resources, and the parameters and the waveform of each output interface of the circuit board are displayed through the software interface. The universal circuit board test system has the advantages that the expandability is high, the universality is high, the automation degree is high, the operation is convenient, and the like.
