Re: Step #3 help from assembly manual ADX-S kit


 

Adam,
Yes the light on the nano is lit no problem there.

Ok, like to know how the 5v regulator isn't working, followed the assembly manual to the letter, so guess I'll have to see if can unsolder nano, or use the 5v regulator like the link showed, but not sure on how it works, only connection was ground and 12v, showed nothing else.

Hi Tim,

There are two regulators on the Arduino Nano board. One is 5V and the other is 3.3V.

It looks like your 5V regulator is damaged, but 3.3V regulator is okay. With 12V on C1, can you still see LED is lit on the Arduino Nano module?

You should be able to proceed with the building still, but you only can power the radio with USB port now. The RF output will be limited to a few hundreds of mW.

The fix is to replace the module, or you can try to add an external regulator like this blog if it applies to your situation.


Thanks,

Adam

Up to testing step #3, testing voltage on + pad of C1, and I get 12v, not 4.93, but I do get 3.41v of left pin of R1, is something wrong here?
