RFID RC522 Reader + Key Fob + Card 13.56 MHz SPI Read/Write for Arduino

Advanced RC522 RFID reader module

The RC522 board is designed for interaction with RFID devices operating at 13.56 MHz. It features a built-in antenna that enables efficient reading and writing of data. The device is powered by 3.3V and uses the SPI interface for communication. Thanks to the integrated antenna, the module ensures stable communication at a distance of up to 10 cm, allowing reading even through non-conductive barriers. The product is ideal for systems that require authentication to perform actions.

Microcontroller compatibility

The module works with all popular platforms. It is intended for use with ESP8266, ESP32, Arduino, Raspberry Pi, and STM32.
