RC522 RFID Reader Writer SPI Module with Card & Tag
The RC522 RFID Reader/Writer Module is a 13.56 MHz non-contact communication module designed for integration with microcontrollers like Arduino, Raspberry Pi, and ESP32 via SPI interface. Operating at 3.3V DC, it supports reading and writing to ISO/IEC 14443 A/MIFARE compatible tags with a typical range of up to 50mm.
Features
- 13.56 MHz operating frequency with SPI interface (up to 10 Mbit/s) for direct microcontroller connection.
- Supports ISO/IEC 14443 A/MIFARE protocol for reading/writing compatible RFID cards and tags.
- Typical read/write distance of up to 50 mm (2-5 cm) for reliable non-contact operation.
- Low power consumption with 13-26mA operating current and 10-13mA idle current.
- Compact 60mm x 39.5mm PCB design with integrated analog demodulation and decoding circuitry.
