Description
The RC522 reads and writes MIFARE Classic 1K cards and tags from a few centimetres away over SPI. With the popular MFRC522 Arduino library you can read a card's unique ID in a few lines of code.
Features
- NXP MFRC522 reader IC, 13.56 MHz
- Reads and writes ISO/IEC 14443A / MIFARE cards
- Read distance up to about 3–5 cm
- SPI interface, 3.3 V supply
- Includes one S50 card and one S50 key-fob tag
Important
Power the module from 3.3 V, not 5 V. Its SPI pins are 5 V tolerant, so it can connect directly to an UNO (SDA→10, SCK→13, MOSI→11, MISO→12, RST→9).
Package includes
1 × RC522 module, 1 × RFID card, 1 × RFID key tag, 1 × straight and 1 × right-angle 8-pin header
