Hello there,
I purchased a Adafruit PN532 NFC/RFID Controller Shield for Arduino but when I ran the stretch and it would display looking for PN532. First I soldered the connecting pins to the shield and then placed the shield on top of the Arduino uno R3 the green power LED stay on constantly and well as the red busy LED.
I then download the library from github(https://github.com/adafruit/Adafruit_NFCShield_I2C), I then placed the uncompressed file with in my Arduino library folder, next I opened the IDE. I found and uploaded the stretch (mifareclassic_formatndef) which went smoothly but when I ran the serial monitor to format the FRID tags but it displayed this . . .
Looking for PN532...

TIMEOUT!
TIMEOUT!
Didn't find PN53x board
I also check the voltages at the pins that are suppose to have voltages and every did, I do not know if that helps. Any suggestions?

What kind of Arduino are you using?
The NFC Shield uses the SDA and SCL pins next to the USB jack, but Arduinos older than the Uno R3 don't have them. If you're using an older Arduino, you can run jumpers from the A4 and A5 pins to the holes that connect to SDA and SCL.

That puts the connections in the right place.
Your soldering looks good and the jumper settings are right, so it sounds like there's a problem with the PN532 itself.
