2ABVM-ELECHNFCV4PN532 NFC BOARD

www.elechouse.com PN532 NFC RFID Module User Guide Version V4 Introduction N ear 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 documents to help developers. We developed this module based on the official documents. To make things easier, we also build library for this module. www.elechouse.com We have updated this module to version 4. Compared with V3 have the following improvement: Performance PN532 NFC V3 PN532 NFC V4 Description Reading Distance on PVC Mifare tag 5~6cm 6~8cm Improved performance on IOS14443A tags Reading Distance on PVC SRT512 1~2cm 2~4cm Improved performance on IOS14443B tags Feature 1. Compatibility: it is compatible with V3 both in hardware and software. 2. Smaller: the size now is as small as 42.7mm*40.4mm*4mm 3. Easy to change mode: with a small SMD toggle Switch, it becomes very easy to change among IIC, SPI and HSU modes 4. Longer distance: the reading distance becomes 6~8cm www.elechouse.com 5. Open source Arduino library 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 6cm~8cm 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 Interface • VCC: 3.3V~5V • Currency: Max 120mA www.elechouse.com • I2C/UART: 3.3V~24V TTL • SPI: 3.3V TTL with 100 ohm resistors in series. It could be connected directly to 5V interface of microcontroller such as Arduino. The I2C and HSU shares the same pins. The definition of IIC pins is printed at front and the HSU’s is printed at the back. The HSU mode is configured as the default mode. But you could change the interface by setting the toggle switch. The switch setting is shown as follows: Working Interface Channel 1 Channel 2 HSU OFF OFF I2C ON OFF SPI OFF ON We break all the PN532 pins out. The 1.27mm connector hole contains those pins which might not be used for most users. If some developers need to connect those pins, we could supply connectors. You could find this product here. Hardware Installation Solder the connector The bended male pins come with the NFC board. www.elechouse.com Some users might need soldering other types of connectors or directly solder wires on it. Anyway, make sure the wires go across the antenna lines in 90 degree. www.elechouse.com Connect with Arduino If without the sensor shield, please connect as following: Mode PN532 Module Arduino UNO Arduino Leonardo Arduino Mega (2560) Arduino Due Power VCC 5V 5V 5V 5V GND GND GND GND GND IIC/I2C Mode SDA A4/SDA Pin 2 /SDA Pin 20 /SDA Pin 20 /SDA SCL A5/SCL Pin 3/SCL Pin 21/SCL Pin 21/SCL HSU Mode TXD Pin 0 Could not present message in Serial Monitor on PC Pin 0 Pin 19 Pin 19 RXD Pin 1 Pin 1 Pin 18 Pin 18 SPI Mode SCK Pin 13 or ICSP-3 ICSP-3 Pin 52 or ICSP-3 ICSP-3 Note: SPI on Due is still in developing MISO Pin 12 or ICSP-1 ICSP-1 Pin 50 or ICSP-1 ICSP-1 MOSI Pin 11 or ICSP-4 ICSP-4 Pin 51 or ICSP-4 ICSP-4 SS Pin 10 Pin 10 Pin 10 Pin 10 Arduino UNO only has one serial interface which is also connected to USB port to PC. In HSU mode, the serial monitor could not be used as message displaying windows. Function Test RFID Reader/Writer Here we show how to read and write RFID card with this module. Download the library PN532 at our github page. You could find 4 folders in the library. Unzip the 4 folders at the library folder in Arduino IDE. Start Arduino IDE and choose the example: www.elechouse.com Modify the code to choose the right mode: Upload the code to Arduino and open Serial monitor. Put a card on it: www.elechouse.com www.elechouse.com You could also try other reading/writing example code in the library. It also supports reading flexible tag. We tested flexible tags of Mifare 1 S50 and Ultralight. The reading distance is up to 5cm. You could find those flexible tags here. P2P NFC Currently we are still developing the software. The P2P NFC communication between two PN532 modules is only supported by I2C mode. Please download this library. Note, while testing this library, please remove the libraries in the testing above (or other PN532 libraries) to other folders. Otherwise they might conflict. Here we need two Arduino boards to test this function. Basically we will program one NFC module as Initiator, and the other as Target. www.elechouse.com Please upload the following two examples to the two Arduino board: • NFC_p2p_initiator • NFC_p2p_target After uploading the sketches, open the Serial Monitor. Please note that Arduino IDE doesn’t support opening 2 Serial Monitors. So you need another Serial Tool. Here we have 2 versions of Arduino IDE installed in my PC: Arduino 0022 and Arduino 1.0. We open the two and could have two Serial Monitor working. Note the baud rate is 115200. Target: Initiator: www.elechouse.com Then put one module above the other: Finally we get ： www.elechouse.com Target: Initiator: NFC with Android phone Download the library of NFC_Module_DEV from our github page. www.elechouse.com Note, while testing this library, please remove the libraries in the testing above (or other PN532 libraries) to other folders. Otherwise they might conflict. Currently this library only supports HSU mode. We are still working on more modes. If you wan…
