Description

Near Field Communication (NFC) is a set of short-range wireless technologies. It's behind daily applications such as access control system and mobile payment system. 

Grove NFC features a highly integrated transceiver module PN532 which handles contactless communication at 13.56MHz. You can read and write a 13.56MHz tag with this module or implement point to point data exchange with two NFCs. Grove NFC is designed to use I2C or UART communication protocols, and UART is the default mode. In addition, we assign an independent PCB antenna which can easily stretch out of any enclosure you use, leaving more room for you to design the exterior of your project.

Can anyone please clarify what and where requires to be cut to make the board work with I2C?

We used I2C interface in the libraries of NDEF, so please cut off the connection between P1 and UART, and solder P1 and I2C together. More information please visit the wiki of Grove - NFC.

Hi Jacket,

I'm running into the same problem. The board doesn't seem to have any obvious connection between UART and P1. Could you upload a photograph on the wiki showing where we'd need to cut? I've soldered P1 and I2C together with no succes

Yep. It would be REALLY helpful if you could show specifically how this is done.
