Send NFC messages using NFC Shield V2.0 by SeeedStudio.
The program uses the standard Arduino shields SPI pins:
| Signal | Pin |
| SCK | D13 |
| MISO | D12 |
| MOSI | D11 |
| CS | D10 |
Note that this shield doesn't use the standard SPI pins, but relies on non-standard 6-pin SPI header located at the shield bottom. To make it work you will have to bridge those pins as shown on the image (the green SPI pins).
| Signal | Pin 1 | Pin 2 |
| MOSI | D11 | SPI4 |
| MISO | D12 | SPI1 |
| SCK | D13 | SPI3 |
