Hi,
I'm playing with the nfc shield with arduino mega, and I need to change the default pins. I followed the tutorial, and cut the trace from IRQ to pin 2, and everything is working just fine. Now I'm adding the data-logger shield, and the project is taller, so I want to de-attach the nfc shield and wire directly to the mega (using the pin from 22 to 53), and I need to change the corresponding pin number (MOSI, SS, etc.). It's possible to do something like in the tutorial, with all the other pins?If it's possible, how I could accomplish that?
Thanks in advance. :D

Ok, I just figure it out that SDA and SCL can't be changed. But, for the reset pin (4), what trace I have to cut, if I had to?

Hey guglio,
The easiest thing for you to do, is just connect wires too the corresponding pins on the shield.
This safes a lot of trouble and you don't accidentally cut a wrong trace.
The other option is to use the breakout board.
Kind regards,
Ralf
