Module detection method:
1. Preliminary quick assessment: disconnect all modules of the module, only supply the module with 5V (i.e. Vcc is connected to 5V, ground), then briefly connect the CK connector of the module with ground and then measure the ground fault. The voltage, which should be 4.5V, and then measure the voltage between DO / RX port and ground, should be about 0V. If the voltage is constant, the module is 99% normal.
2. Complete the test rating: use the test circuit diagram provided in the shop to create a circuit, enter the 89c51 single chip computer into the hex test program of the store, connect the computer with the serial cable, and run the serial port wizard on the computer, you can get the test circuit. The measured value is reported and the measured value is normal, which indicates that the module is normal. Please refer to the following test table for details.
