Use Arduino Leonardo Board instead

[cbDragon]

Hey guys, I am really appreciated with your great work about the PN532. I am a novice in Arduino field. However, I wonder if I use Arduino Leonardo to do the experiment, anything need to be changed? For example, the wire connection I found in the elechouse pdf may be different between this two development board.

I never used an Arduino Leonardo board before, so cannot be sure... but as boards follow Arduino connector standards:

• SPI (CLK, MOSI & MISO) are on same SPI pins (13, 11 & 12) ;
• Interrupts are on same interruptable pins (2 & 3) ;

it should work.
