magagalit ang mga hapon pero pwde na pangtest lang kung gusto mo malaman kung working ang load mo.

ung mga 3 pins reg ay bale DC INPUT -GROUND-DC OUTPUT

ung mga 4 pins reg ay DC INPUT -GROUND -DC OUTPUT- switching input (ON-OFF control) , ndi pa magttrigger ang DC OUTPUT once na wala pang nagswitch sa ON_OFF control ng device!

ok na po ang unit.... pinalitan ko ang 120rda1 at kapiranggot na capacitor connected sa 3.3v regulator near i2c dahil binabagsak nya ang 3.3v
