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.
Working Voltage: 3.3V
Working Current: Static Mode: 73mA, Write/Read Mode: 83mA
Support host interface: I2C, UART(default).
Serve for contactless communication at 13.56MHz.
Support ISO14443 Type A and Type B protocols.
Max operating distance for detecting NFC tags is 28mm depending on current antenna size.
Support P2P communication.
Dimensions: 25.43mm x 20.35mm

I am using the NFC reader with I2C on an Arduino EVM. I want to ask how to send power down command to set the reader into soft power down mode, and how to wake up from RF detected. ThanksQuestion by: Hu Neil on 2019-03-19 10:12:51
I am using the reader with UART on a Arduino Mega, the board is detected but when I have tried using ISO14443 tags the reader is not detecting them, is there a standard tag that you have found that works? Also I have not been able to get I2C to detect the board at all, any ideas? I have read the wiki pages and searched forums but nothing is clear or works.Question by: admin on 2018-12-18 02:21:11

How many readers can I connect to one arduino? We need to have 9 or 12 readers for a game we're creating.Question by: admin on 2018-12-18 02:20:55
Thanks for your quick reply! Does it also read MIFARE cards?Answer by: admin on 2018-12-18 02:20:55
