NFC
is a popular technology in recent years. We often heard this work
while smartphone company such as Samsung or HTC 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 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.
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. On this module, I2C is the data Interface by
default. 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 break
out those pins. Description: 1.Small dimension and easy to embed into your project 2.Support I2C, SPI and HSU (High Speed UART), easy to change between those modes 3.Support RFID reading and writing, P2P communication with peers, NFC with Android phone 4.RFID reader/writer supports: 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 5.FeliCa cards such as RCS_860 and RCS_854 Up to 5cm~7cm reading distance 6.On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL SPI 7.Arduino compatible, plug in and play with our shield Feature : 1、Gilt PCB and Small dimension and easy to embed into your project 2、Support I2C、SPI and HSU (High Speed UART), Change between those modes 3、Support RFID reading and writing SupportP2P communication with peers Support NFC with Android phone 4、Typical Operating Distance have been updated to 5cm~7cm reading distance 5、Work in NFC Mode or RFID reader/writer Mode 6、RFID reader/writer supports: 1) Mifare 1k, 4k, Ultralight, and DesFire cards 2) ISO/IEC 14443-4 cards such as CD97BX, CD light, Desfire, P5CN072 (SMX) 3) Innovision Jewel cards such as IRT5001 card 4) FeliCa cards such as RCS_860 and RCS_854 7、Plug and play, Arduino compatible 8、Built in PCB Antenna, with 4cm~6cm communication distance 9、On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL SPI 10、Work as RFID reader/writer 11、Work as 1443-A card or a virtual card 12、Exchange data with other NFC devices such as smartphone Interface : The version 3 can support I2C、SPI and HSU (High Speed UART), there is a switch can help you to change interface between those modes easily.
