I found this to be rock solid with an Arduino. I was never able to get it working in the ESP32's 3.3v environment, but that could have been user error.Highly recommended for Arduino though.

I have used PN532 from this and other vendors in several projects before. Recently had trouble reading some custom tags, so I bought a NanoVNA to measure the resonant frequency of these modules and the tags. Tested 5 of the PN532 modules and found that each had a different resonant frequency, ranging from 12.6-15 MHz. None were tuned to 13.56 MHz. The read range for the included tags, and a custom tag tuned to 13.6 MHz, is 3-4cm.

This module offers fast uart, I2C and SPI all in one! It works beautifully ! I've installed it as part of my smart car project, connected to an Arduino board through I2C. Even with high temperatures inside the car under the Texas Sun, it has been working without any trouble. If need be you can also change the address of the module for I2C. You can find libraries already there for Arduino as well. All in all, this is one of the better modules!

Good value, reliable and easy to work with

Works but documentation is terrible. Couldn't get working except in I2C mode and requires 6 wires when you're provided 4.
