PN532 NFC RFID Module V5

PN532 NFC RFID Module V5

Description 

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. It supports multiple contactless communication protocols and is perfect for payment systems, access control, and IoT applications. And the company offers much technology document to help developers. And in order to make things easier, we also build library for this module.

We guarantee that all of our PN5321A3HN/C106 is 100% original from NXP, we can guaranteethe the performance stability of PN532 NFC RFID Module V5 !

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, 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.

PN532 NFC RFID Module V5 is the newest updated version from PN532 NFC RFID Module V3.

Note: PN532 NFC RFID Module V5 is completely compatible with V3 on hardware and software. V5 also keeps exactly the same shape, installing holes and interface as V3.

Improved PCBA design、optimization of parameters and circuit, and wider bandwidth of antenna,  all of these optimized factors make PN532 NFC RFID Module V5 perform much better than V3.

6、Plug and play, compatible with Arduino、ESP32 and Raspberry Pi 

7、On-board level shifter, Standard 5V TTL for I2C and UART, 3.3V TTL for SPI

8、Size: 42.7mm*40.4mm*4mm

Dimension

Interface

The version 5 can support I2C、SPI and HSU (High Speed UART), there is a switch can help you to change interface between those modes easily.

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.

Connection with Arduino

Application 

1、Access control systems (door locks, attendance tracking)

2、NFC tag reading and writing (NDEF, MIFARE)

3、Android phone NFC communication

4、Smart card emulation and verification

5、IoT device authentication

6、Maker projects requiring multi-protocol NFC support

Getting Started

Step 1: Select your interface mode by setting the solder jumpers (I2C, SPI, or HSU)

Step 2: Connect the module to your Arduino or microcontroller using the selected interface

Step 3: Download and install the PN532 Arduino Library

Step 4: Open one of the provided examples (e.g., readMifare) and upload to your board

Step 5: Open the Serial Monitor at 115200 baud to view tag data
