3. HiLetgo PN532 NFC NXP RFID Module V3 Kit Near Field Communication Reader Module Kit

RFID Arduino

The HiLetgo PN532 NFC RFID Module is a highly integrated NFC transmission module. The mode switch lets you swap between I2C, SPI, and UART modes. The integrated level shifter provides 3.3V or 5V voltage. 

It supports RFID reading and writing and NFC function with Android phones, allowing for easy wireless connection. 

Features

  • I2C, SPI, and HSU (High-Speed UART) support, with easy to switch modes
  • Can be used in NFC and RFID reader/writer mode
  • Integrated 3.3V voltage regulator provides 3.3V or 5V working voltage
  • 3 cm maximum communication distance

When enabled, the PN532 transmission module can answer a reader/writer command according to FeltCa or IS014443 A / MIFARE® card interface mode. The PN532 generates the digital load-modulated signals, and in addition to an external circuit, you can send the answers back to the reader/writer. Complete card functionality is only possible with a secure memory IC. 

Additionally, the PN532 transmission module offers the possibility to communicate directly to a second NFCIP-1 device in the NFCIP-1 mode. The NFC-1 mode offers communication transfer speeds up to 424 kbit/s according to the ECMA 340 NFCIP-1 Standard. 

The digital part handles the complete NFCIP-1 framing and error detection. Transfer speeds on the RF interface above 424 kbit/s are supported by the digital part of the PN532 module. An external circuit has to do the modulation to transmit and the demodulation to receive data at transfer speeds.

What We Like

  • 80051 microcontroller core with 40 kbyte ROM and 1 byte RAM 
  • Highly integrated analog circuitry to demodulate and decode responses 
  • Buffered output drivers to connect an antenna with minimum number of external components 
  • Integrated RF Level detector and Integrated data mode detector
  • Supports ISO 14443A / MIFARE 
  • Supports ISO 14443B in reader/writer mode only 
  • A typical operating distance in reader/writer mode for communication to an IS014443A/MIFARE, IS014443B, or FeliCant card of up to 50 mm, depending on the antenna size and tuning 
  • A typical operating distance in NFCIP-1 mode of up to 50 mm, depending on the antenna size, tuning, and power supply 
  • A typical operating distance in IS014443A / MIFARE® card or FeliCam” card interface mode of about 100 mm depending on the antenna size and tuning and the external field strength 
  • Supports MIFARE Classic encryption in readerNidter mode and MIFARE higher transfer speed communication at 212 kbit/s and 424 kbit/s 
  • Supports contactless communication according to the FeIiCaTM scheme at 212 kbaud and 424 kbaud. Integrated RF interface for NFCIP-1 up to 424 kBaud 
  • Possibility to communicate on the RF interface above 424 kbaud using external analog circuitry

What We Don’t Like

  • Some users complained that they have significantly less range than others. They do not work well with glass tube NFC implants at all.
  • Some users complained that, in the manufacturing process, two resistors were 10K instead of 100Ohm.

Things to Keep in Mind When Buying an RFID Arduino Reader

The Value of a Brand

Why would you choose to spend your money on a less expensive brand if it cannot live up to your standards? A well-known brand will prioritize the maintenance of its reputation above all other considerations. There is a greater possibility that it will not be dependable.
