RC522: 13.56MHz RFID Reader / Writer Module
The RC522 is a highly integrated MFRC522 contactless communication chip designed for radio-frequency identification at 13.56MHz. It is the industry standard for low-cost RFID applications. Whether you need to read an ID card or write data to a key fob, the RC522 provides a stable and reliable SPI-based connection to your R1BBIT controller.
- Contactless Communication: Fast and secure data exchange within a 0–50mm range.
- Standard Support: Fully compatible with ISO/IEC 14443 A cards and Mifare classic tags.
- SPI Interface: Low-pin count connection, leaving more GPIOs free for your R1BBIT PICO projects.
- Compact & Efficient: Low power consumption and a small footprint for integrated security panels.
