🔮 PN532 NFC NXP RFID Module V3 Kit - Near Field Communication Reader Module Kit - I2C SPI HSU with S50 and CUID White Card Key Card - Compatible with Arduino, Raspberry Pi, DIY Smart Phone, Android Phone - Black with Pin Header Review

This board is not recognized by Arduino UNO R3 in SPI configuration. I have another board that looks the same as this one but is from Hiletgo and works great right out of the box. I will be returning this board.

This module offers fast UART, I2C and SPI in one! It works great! I installed it as part of my smart car project by connecting it to an Arduino board via I2C. Even at high temperatures in the car under the scorching Texas sun, it worked without any problems. If necessary, you can also change the module address for I2C. You can also find libraries for Arduino. In general, this is one of the best modules!

Works but the documentation is terrible. Can only work in I2C mode and needs 6 wires if you are equipped with 4.

I have used PN532 from this and other manufacturers in several projects in the past. I've been having trouble reading some custom tags recently, so I bought a NanoVNA to measure the resonant frequency of those modules and tags. We tested 5 PN532 modules and found that each of them has a different resonant frequency in the 12.6-15MHz range. None of them were tuned to 13.56MHz. The read range of enabled tags and a custom tag set to 13.6MHz is 3-4 cm.
