  • Advanced RFID kit for Raspberry Pi and Arduino projects
  • MFRC522 chip enables 13.56 MHz contactless communication
  • Includes S-50 white card and key ring for immediate testing
  • 3 V SPI interface connects directly to CPU boards
  • Package contains module, two pin headers, card and key ring

RFID-RC522 Kit for Microcontroller Projects

This kit provides an MFRC522-based reader module operating at 13.56 MHz with an SPI interface. It includes an S-50 card and a key-ring tag for immediate testing. The module runs on 3.3 V logic and suits hobbyists adding contactless identification to Arduino or Raspberry Pi builds.

Supported Card Types and Read Range

The reader handles ISO 14443A transponders including Mifare 1 S-50, S70, UltraLight, Pro and Desfire cards. Typical read distance reaches a few centimetres depending on antenna tuning and tag orientation. Metal surfaces or thick enclosures will reduce reliable coupling.

3.3 V SPI Interface Requirement

The module communicates over a 3.3 V SPI bus and is not 5 V tolerant on its signal pins. Direct connection to 5 V microcontrollers without level shifting can damage the IC. Verify that your host board provides a 3.3 V SPI port or add a logic-level converter before wiring.

Questions about this item

Will the RFID-RC522 module work with an older Arduino Uno that only has 5 V logic pins?

The module runs at 3.3 V and communicates over SPI; a logic-level shifter or resistor divider is needed to connect safely to 5 V boards.

How can I verify the reader is functioning after wiring it to my Raspberry Pi?

Power the Pi, enable SPI in raspi-config, then run a simple Python script using the MFRC522 library; the console should print the UID of the supplied S-50 card when it is presented.

What comes in the box and do I need any extra parts to start?

The kit includes one RFID-RC522 sensor module, one S-50 white card, one key-ring tag, one vertical pin header and one curved pin header; you will still need jumper wires and a 3.3 V-capable host board.
