The Best RFID Modules for M5StickC Plus

M5StickC Plus contains 2 versions, the red one is v1.1, the organge one is v2. The main difference is the MCU and battery lifetime. And the Grove socket and PINs out are the same. In this article, let’s check the best RFID Modules for M5StickC Plus.

Device Ranking

  1. PN532 Module
  2. PN532Killer
  3. Unit RFID2

PN532Killer

PN532Killer is the only module that supports both ISO14443A, ISO15693 and EM4100. It supports only UART via FPC connector. It has has the bult-in USB Serial chip which can use as a USB RFID Reader. To work with M5StickC Plus, the Adapter is necessry for M5Stick Plug and Play.

What does PN532Killer can do with M5StickC

  • Tag Reader
  • Emulator Slot Controller
  • Sniffer Controller
  • BLE Extension Mode

Emulator Mode

M5StickC Plus can control the PN532Killer emulator from Slot 1 to Slot 8 for Mifare Classic 1K and the ISO15693 tag.

Reader Mode

M5StickC Plus can read the tag UID and protocol type by one click and show the UID on the screen.

Sniffer Mode

M5StickC Plus can control the PN532Killer to do MFKey cracking by Sniffing without tag and Sniffing with tag.

BLE Module

This is the most exciting part. M5Stick Plus can be the BLE module for PN532Killer, so they are a complete BLE reader can be connected to MTools BLE App for Mfiare Classic Tag reading and writing, MFKey32v2 attacking, MFKey64 attacking and uploading the dump data to the slot.


PN532 Module

The most cost effective RFID Module that supports on ISO14443A HF 13.56MHz, which include Mifare Classic, Mifare Ultralight and Mifare DESFire, also the Felica protocol.

Supported Communication Protocols
