HiLetgo PN532 NFC RFID Module V3 Kit Near Field Communication to Smart Phone Android

It worked nice thank you

After I got a replacement, this worked great having gone on a fun with my raspberry pie and ESP32 device devices. Most difficult part about it is making sure you have the right code to actually run this. There’s plenty of premade stuff out there that will help.

Bought this as a cheap way to see if an NFC project was feasible, and it works using both the included tags and some NTAG213 stickers found elsewhere on amazon. I soldered in one of the included 4-pin headers, and then used that to connect an FTDI TTL-232R-5V usb-to-ttl-serial cable. It then comes right up and works with libnfc and the libnfc examples, after putting the proper serial port into /etc/nfc/libnfc.conf . I'll be ordering a few more. Two little things that didn't bother me: only has a 4-pin connector, so I had to put a custom matching 4 pin connector onto the FTDI cable. If this had a compatible 6-pin connector, I could have used an unmodified FTDI cable or other usb-ttl-serial adapter with the common 6 pin header. The set of three wires were not included in my package.

The product shipped from Amazon is not V3 as shown in the picture. It is an older version that does not have the Reset pin break out (Required for Adafruit python I2C library). I followed the instructions but could not get it to work with the Adafruit Python library for the Raspberry Pi (either I2C or SPI). It may work with Arduino but you will have trouble with the Raspberry Pi Python library. [UPDATE] It must be some problem with my old Raspberry Pi board, but I swapped in a Raspberry Pi 3 board and installed Adafruit's adafruit-pn532-rfid-nfc circuitpython and everything is working now. Even the board I bought is not version 3 and does not have the reset pin, it still works.

This review is for HiLetgo PN532 RFID Module. The package comes with 2 RFID cards (1 card and 1 key fob style) and the module itself. The module claims it can support 3 kinds (HSV, I2C and SPI) of connection. Most of the time, I would choose I2C as it has less wires to connect. But this is not the case here. The first reason was that in order to use I2C, you need to connect RST0 and IRQ pins (Based on the Adafruit library). Also, although the library can support both I2C and SPI, I could not find the initialize routine can pass in any I2C address. I might have missed something. Anyhow, given all these, I end up used SPI as my wiring between Arduino and the board which turns out working really well. Another good thing about SPI is that the library supports SW SPI, so I can choose whatever digital pins that I want. I used pin 2 to pin 5 as the example sketch suggested. For my testing, I used my Arduino UNO and open one of the example sketches provided by Adafruit. I had no problem reading the card. I am happy with the result. I would recommend this board for anyone who would like to learn more about 13.56Mhz type of RFID and how to use Arduino to control it.
