【NFC module】Adopts PN532 transceiver, which can handle contactless communication at 13.56MHz, or use two NFC Shields to achieve point-to-point data exchange. 【Used as PFID reader】It can be used as a PFID reader for Mifare one tags and cards (13.56 MHz). 【Support multiple protocols】Support P2P communication, support ISO14443 type A and type B protocols. 【2 types of interfaces】Support UART, IIC (default) interface.
The Crowtail-NFCmodule (Near Field Communications) uses a highly integrated transceiver module PN532 which handles contactless communication at 13.56MHz. It is designed to use IIC (default) communication protocols. In addition, you can also use UART communication protocols via change the connection between the welded plates.
You can read and write a 13.56MHz tag with this module or implement point to point data exchange with two NFC Shields.
Features
Uses as a PFID reader with Mifare one tags and cards(13.56 MHz).
It can support UART, IIC(default) interfaces.
It has 13.56MHz independent PCB antenna.
Max operating distance for detecting NFC tags is 28mm depending on current antenna size.
