再請教 K.K._ Ucd_400 ad 關機有吱吱聲
Dear K.K.Do you mean to apply a DC voltage to "J4 & Ground" ?
My transformer has an additional "12 X2 " (AC)
Please show me how !!
Thanks !

FYI Thanks !Already done ! Old boy,
Please let me know you are solving the problem or not ?
Thanks
KK.HO It works now !
Thanks ! Thanks. Turning the module off is OK. But the problem is turning it on. When /on is pull to GND, I can hear a loud "pop" 1 -2 seconds later. Did you place a large cap in the EN pin ? I did not put any caps in the EN pin
