Emm, actually I have made the board at Tuesday, but I get wrong part…😂

My stupid mistake: I plan to use MP3202DJ to powerup the WLED, then I find SY7200AABC have better parameters and price is lower, but forget check its output voltage is 30V and feedback voltage is also double, which is exceed my output cap max allowed voltage…I get a super sudden current when I boot it up, just hope my LCD backlight is still working after the accident.😖

Please lend me a corner and let me cry for a while …
