Hi,
I have an Arduino Uno R3 and SeeedStudio NFC Shield V2.0.
I downloaded the library for the NFC Shield V2.0, http://www.seeedstudio.com/wiki/File:PN532_SPI_V2.zip.
I connected the shiled at the board by headers (I found in the package).
I connect shield and board by USB cable at my computer and I tried the example (Read All Memory Blocks) and I got the error "Didn't find PN53x board".
I checked the power supply at the shield and the display's multimeter's show 5V.
I used external power supply, 12V - 1A and 9V - 500mA, but I got the same error.
What is the error?
must I change some parameters of the sketch or must I check other on the board/shield?

I connected the shiled at the board by headers (I found in the package).
Did you solder the headers in place?

Hi,
I'm not soldered the headers.
I found the headers in package.
I attached a picture of board and shield.
Thanks

PaulS:
I'm not soldered the headers.
Then do so.
I use the headers or I must solder

You must solder the headers, or wires if you don't want to mount the shield on the Arduino, to the board.

Hi,
I soldered the headers (Foto 2.jpg and Foto 3 .jpg).
I tried the examples but I have the same error: "Didn't find PN53x board".
I connected a led on the headers of the NFC Shield (Pin 13 and GND), and I tried the Blink example and the led is on (Foto 1.jpg).
The Shield is not compatible with Arduino Uno R3?
