Topic: NKC RGB LCD shield causes disconnection (Read 1 time) previous topic - next topic


Howdy!  I'm using the Duemilanove with an atmega328, and I've recently assembled NKC Electronics' 'RGB LCD Shield for Arduino.'  Go Team Phil!  But wait!  There's more!  When I plug the darn thing into my arduino, the arduino suffers a total communication loss with the PC.  To the point that it even loses power.  I've checked my connections again, and checked my assembly vs. assembly guide.  Then I had my brother check everything over (he's better at this than me).

So, basically what I'm wondering is if anyone else has tried using this shield, and if they've had the same problem, or if it worked.  And if it didn't work, then whether they found a resolution.



It is possible that your supply is not able to provide the current. Have you tried using an external power supply?

I am having the same problem. When I plug the LCD Shield, the arduino powered off.


After doing some test, I figure it out that there is a short circuit between the VCC pin and GND pin. But I cant found where is the short circuit. All the solder points are OK. No apparent short circuit on the solder points.

Any help will be apreciate.



@WestNQ: can you send me hi-res pictures of the top and bottom of the board to support at nkcelectronics dot com?
