>> Hi All
>>
>> Yesterday I finally managed to fix my airplane after my last incident and
>> began to reinstall the Tiny.
>> When everything was connected and I had wrapped the board in some foam I
>> thought I should test everything before the final installation. I had
>> everything tested OK outside of the plane the day before. But this time when
>> I connected the battery a very bad sound was heard from the Tiny. It sounded
>> like a very bad short cut!
>> I immediately disconnected the battery and tried to see if anything was
>> burnt but I cannot find anything that looks broken. I tried one more time to
>> connect the battery but this time nothing happens. The thing is dead! :-(
>>
>> After I while I decide to try to locate the fault. I think it looks now
>> like the power supply, the PTH08080WAH module, is broken. When there is
>> power connected to it it does not give me +5V on the output pin. I should be
>> able to just measure on the output pin against ground, right?
>>
>> The question for you guys now is if it possible to change that module?
>> Of course it is possible but I mean more if you think it possible that the
>> rest of Tiny has survived and that the module is the only thing broken? Is
>> it worth a try?
>>
