I just purchased a WAV Trigger (WIG-13660 ) all was great until I plugged in a 12v AC wall wart. Why in the world I have a 12v AC is beyond me, but i accidently picked it up, plugged it in, and out came the magic smoke.
Could anyone help tell me what voltage regulator is on this board so i can replace it and hope that it’ll still work?
I tried to match the one in the websites stock photo but no luck, i zoomed into the one a burned out and the only imprint i see on it is GH15228J14. That number doesn’t feel familiar at all and most people say it’s an LM117.
Any feedback would be helpful, thank you in advance.
Thank you for the information. After review of the LM1117 datasheet i see there are multiple subtypes (e.g. LM1117-2.5) which have different specs. Anyone have advice on maybe specifically which LM117 subtype the WAV Trigger requires?
If @TS-Russell is around later in the week he should be able to look up the exact part number sparkfun uses but I’m fairly certain the link above should do the trick.
Also, if you want to test the board before buying another regulator, you can apply a regulated 5 volt supply to the 5Vin and GND pads in the corner of the board. You do need to close the 5v jumper that’s next to the headphones jack and remove the bad regulator ic to do so.
If the board works after doing that it should work OK after replacing the regulator.
Apologies for the incorrect link before, I’m replying via mobile and fat fingered it.
@YellowDog thank you for all the quick replies. And this one most specefically, going above and beyond to help me understand exactly how to test the board. I’m going to try exactly as you said, tonight, and I’ll post back. Maybe this will help other, although I think I’m the only idiot to have a 12v AC wall-wart
