UHF RfID PN532 NFC Emulator PN532Killer NFC relay nfc sNIFFER

This project was created on 07/15/2025 and last updated 4 months ago.

Description

As we know, the PN532 has been discontinued, but it is still widely used in many fields.
Having previously implemented a USB NFC reader using the AD15N, I began to wonder if it would be feasible to leverage the AD15N to emulate the functionality of the PN532.
Boasting ample performance headroom, the AD15N is more than capable of accurately emulating the core functions of the PN532—giving rise to the PN532Killer.

The basic functions of PN532Killer are as follows:
Reader: ISO14443A/B, ISO15693, Felica
Tag Emulator: ISO14443A(Mifare 1, Ntag), ISO15693 tag, EM4001(Implemented using an expansion board)
NFC Relay: ISO14443A relay, Implemented using an expansion board -- Raspberry Pi Picow or Pico2w
NFC Protocol Analyzer: ISO14443A Protocol Analyzer
