Hi,

I've a problem with my Shield 3G/GPRS for Arduino and Raspberry
https://www.cooking-hacks.com/3g-gprs-shield-for-arduino-3g-gps :
When I plug this shield on a Arduino Uno board, with both power supplies (usb and jack), the Arduino board burns down... I tried with 7 boards and now, I get 7 stuff out of work :lol:.

I checked all the jumpers, they are on the right position since the first time, I plug out all the power supplies every time I plug on or plug out the shield in order to avoid some problems. Every codes I tried are from the tutorial.

If anybody can help me to find where is the problem from it would be grateful!

Thanks !

Hi Ben_90,

Can you upload some photos of the 3G board? We want to see the configuration of the jumpers and how do you connect all.

Also, is the jack power labeled with some information? Please upload a photo of it.

Which part of the Arduino is burned?

Thanks.

Regards

Thanks for your reply !

Please check the pictures that I putted on the folder.
Their is a picture of the power supply, one of the arduino board and two or three of the 3G board.

Thanks for your help!

Best regards

Ben

Hi Ben_90,

An what about if you use the 3G shield using the USB cable, can you upload sketches to the Arduino? Do you see the led of the arduino working or something?

Give us more information because in the photos we can't see something estrange.

Thanks.

Regards

Hello,

Yes I tried with the USB cable on the shield but it's not recognised by the Arduino IDE.

Ok so the really firsts times I tried, there wasn't any problem, I plugged the shield on the Arduino and it worked. I succeeded in calling someone, sending one SMS every 5s... But one day it began to burn out some Arduino boards. I think that I uploaded several sketches on the Arduino without removing the 3G board. I really don't know if the problem comes from that mistake or not but the fact remains that it works randomly.

There are 2 cases for Arduinos that I destroyed:
- The first case is a board detected on the laptop but impossible to upload any sketches! There are 2 led always alight: the "ON" green LED and the "L" LED.
- The second case, the most frequently is a overheating of the board when I plug the 3G shield and run the program. Once burnt it's undetectable by the laptop.

The procedure that I try to follow is:
- uploading the program on the Arduino board with out any shields
- unplugging the Arduino from the laptop
- plugging the 3G shield
- plugging on the USB cable on the Arduino & opening the serial monitor
- plugging the power supply (12V DC, 1A)

The last time I followed exactly this procedure, the first time it worked, and the second time it burnt.

I hope these informations will be able to help you to understand.

Regards

Ben
