Add an EMI filter (a small X-capacitor and a common mode choke) before the input capacitor to reduce switching noise sent back into the main grid.
By focusing on these specific hardware enhancements, the performance of the WX-DC12003 can be significantly improved for demanding electronics projects. Share public link wxdc12003 schematic better

The search for a alternative stems from a common engineering headache: the stock WX-DC12003 switching power supply module is incredibly cheap and compact, but its bare-minimum design often introduces severe electrical noise, RF interference, and reliability risks. To build a safer, cleaner, and more robust hardware project, modifying the existing circuit topology or replacing it with an optimized custom layout is essential.
A "better" WXDC12003 schematic must achieve:
