By setting up the B0505XT chip, ISO7221 isolator and optocoupler, the power supply and the signals are isolated separately, so as to prevent the noise current on the data bus or other circuits from entering the local ground or interfering with or damaging the sensitive circuits, thereby ensuring the stability of the controller.
