Hello there
I have some problems with my RFID-Shield. I got it yesterday, did all the soldering, downloaded the library from Github, installed it and so on . I used the readMifare example, opend the serial monitor and got the message " didn't find the PN53x board".
So i checked my solerding twice, downloaded the library again, but the result is still the same.
I rode all of the posts in this forum, but i cant figure out why it isnt working.
The busy and the power led are on permanent. Doesn't matter if i put an card at the shield or not.
I am using an Mega 2560 R3. The tutorial says that it should be no problem with the R3.
So I hope someone can help me with this..
Thanks from Germany and sorry for my english

Re: Trouble with the PN 532 RFID Shield
You solder joints look good, but they are on the wrong side. Installed that way, the header pins may not be long enough to make solid contact. They should be installed from the bottom side and soldered on the top as below.
