10PCS PN532 NFC RFID Wireless Module V3 User Kits Reader Writer Mode NFC is a popular technology in recent years. We often heard this work while smart phone company such as for or introduces their latest high-end phones. Almost all the high-end phone in the market support NFC. Near field communication (NFC) is a set of standards for smart phones and similar devices to establish radio communication with each other by touching them together or bringing them into close proximity, usually no more than a few centimeters. For electronics geeks, we also want to use NFC technology to make our own things. So we build this NFC RFID module. This module is built around NXP PN532. NXP PN532 is very popular in NFC area. And the company offers much technology document to help developers. We developed this module based on the official document. And to make things easier, we also build library for this module. We almost break out all the IO pins of NXP532 on this module. Users could easily connect and play. With our for Sensor Shield, it is very easy to plug and play. However, if users want to use other interface such as UART or SPI, this module also makes it easy to connect those pins.
