Hi everybody;
i need your help to fix my rf module that i broke...
when i measure vcc and gnd, i can see there is a short circuit.
i noticed there were two parts broken which marks 3L33 and 14VF on my modul.
But i couldn't find components that i would use instead of 3L33 and 14VF...
i put a picture for looking at the components and my modul..

Thank you....

 

hi 34,
Welcome to AAC,
If they are just broken off and the IC's have all their pins, you could solder them back onto board.?

You can search the internet for the device markings.

I searched for 14VF and it appears to be a step down converter:

i think that i used wrong word, i wanted to say my components were burned
i hope i use correct word....

 

is the short gone now with these removed? which one, or both?
