PN532 (HSU) drivers for ESP32 using ESP-IDF, and full PCB design for NFC reader.

ESP32-PN532

PN532 (HSU) library

• Platform: ESP-IDF (e.g. ESP32)
• Can work with DESFireAES library for NXP MIFARE DESFire EV1 cards
• See include file for details of functions

Includes KiCad PCB design for PN532 based NFC reader board and 3D case designs. Unlike some NFC boards this includes three traffic light LEDs, a tamper switch, and external contacts for a door bell push, all accessable as GPIO over the HSU connection.

esp32-pn532's Issues

Please make an example

Hello.

I don't know if this is still maintained or not, but I would really love an example on how to use this library.

I am currently trying to integrate RFID1356MIFARE with ESP32-EVB but with no luck.

Thank you.

Interesting project.

Nice project.

I did some, too much, time ago for the office where I work, a NFC reader to count the number of coffees each one is drinking. We all have some NFC access IDs with unique ID number. The device is made out of the Wemos D1 Mini, a SD card adapter, an OLED display, a PN532 dev-board (the bigger blue one) and a custom board to glue everything together. It is all in my GitHub.

Now that our team has expanded was needed to build another one and it was so hard to find similar parts that are working like the old one. The software is also old and I just found the binary from back then and programmed the new board. After a lot of stress and debugging I managed to make a new device. This made me thinking I should try to build a new version with newer components.

Do you think that the PN532 is still the way to go for a NFC reader?
I need to mention that the IDs are of some Desfire type so I guess are more special then the regular NFC coins and need some features. The usual MFRC522 is not good enough.

I think that the ESP + NFC chip + SD card shall be integrated on one board.
The device I am thinking of does not have to be too small, it shall accommodate for an off the shelf >2.5" display.

Can the NFC antenna be bigger than a credit card?
For me antennas are some sort of voodoo magic.

Hello,Master..

This PCB does not have SPI mode. I have checked that it only has HSU and I2C modes. I hope you can add SPI mode. Then I will be very happy, Thank for you!

Code sample using library fucntions

Hi, would you mind providing a code sample using the library functions?

I'm begineer in nfc and I'm not sure on how to use it.

Thank you very much in advance.

The project symbol library cache file 'PN532-cache.lib' was not found.

Hi revk,
Thanks for your awesome work!!

I'm working on making an ESP32-based board (ESP32-H2 once it's available) with NFC. Currently, I'm trying to get some inspiration from your project ;-).

Unfortunately, when I open the KiCad schematic file, I'm getting the following error: "The project symbol library cache file 'PN532-cache.lib' was not found." Am I doing something wrong or is it looking for a file that's not in the repo?

Thanks again!

Assembled boards

Revk do you sell an assembled board? I want to do some experiments to start and cook want to green up board fan for unit one.
