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.

We have developed more than 400 Grove modules, covering a wide range of applications that can fulfil various needs. Click to explore the Grove Sensor family and get started to Grove your Idea. For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface – Getting Started and Introduction to Grove before your use of the product.
