Hi there,

Today I noticed that my Netduino Plus 2 shuts down after a few seconds. E.g. my blinking LED stops blinking, so program execution seems to have stopped.

 

Could that be due to the power supply? I have a 5V supply connected to the USB connector of the Netduino. After doing a little measurement it seems that the supply's voltage is actually between 5.2 and 5.3 Volts.

Is that too much? Could it cause the Netduino to shut down?

 

Or should I look for any other problems?

Hi VanKurt, It's most likely a code issue. Is your thread going out of scope by any chance? Is this the standard "while(true)" blinky demo? USB power from 4.5V to 5.5V is fine. Chris

Hi,

I just realized I did some wrong interpretations there. Actually it seems as if the Netduino ist damaged:

 

The white and blue LEDs are now blinking constantly (also the Netduino "beeps" while the LEDs are blinking). It is not recognized by the PC anymore, too.

 

No matter what power Supply I use (5V from PC or smartphone charger, or 9V DC power supply) the problem won't go away.

So I guess the Netduino is fried?

Hi VanKurt, Unplug your Netduino. Disconnect everything from it. Then hold down its pushbutton and, while holding down the pushbutton, plug it into your PC via USB. Finally release the pushbutton. Does it exhibit the same behavior? If yes, then your Netduino got damaged If not, then try erasing it and reflashing it. Generally speaking this sounds like a damaged power supply. Chris

Sadly I can't manage to revive my little Netduino 

So I guess I'll replace both, the power supply and the Board...

 

Thanks for your help!
