www.elechouse.com PN532 NFC RFID Module User Guide Version 3 Introduction NFC is a popular technology in recent years. We often heard this word while smart phone company such as Samsung or HTC introduces their latest high-end phones. Almost all the high-end phones in the market support NFC. Near field communication (NFC) is a set of standards for smartphones 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. 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 Arduino 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.
www.elechouse.com We have updated this module to version 3. Compared with V2, V3 have the following improvement: 1. Smaller: the size now is as small as 42.7mm*40.4mm*4mm 2. Easy to change mode: with a small SMD toggle Switch, it becomes very easy to change among IIC, SPI and HSU modes 3. Longer distance: the reading distance becomes 5~7cm, compared with 4~6 cm of last version 4. Add software to support NFC with Android Phone Features 1. Support II2, SPI and HSU (High Speed UART) 2. RFID reader/writer mode support  Mifare 1k, 4k, Ultralight, and DesFire cards  ISO/IEC 14443-4 cards such as CD97BX, CD light, DesFire, P5CN072 (SMX)  Innovision Jewel cards such as IRT5001 card  FeliCa cards such as RCS_860 and RCS_854 3. Plug and play, Arduino compatible 4. Built in PCB Antenna, with 5cm~7cm communication distance 5. On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL SPI 6. Work as RFID reader/writer 7. Work as 1443-A card or a virtual card 8. Support NFC with Android phone 9. Small size: 43mm*41mm*4mm
