The RFID Module RC522 Kit is an affordable, easy-to-use RFID reader based on the MFRC522 IC, suitable for a variety of applications. The MFRC522 is a highly integrated reader/writer chip designed for 13.56 MHz contactless communication.
Features:
- Highly integrated modulation and demodulation circuitry.
- Requires only a few external components to connect the output driver to the antenna.
- Supports ISO/IEC 14443 Type A and MIFARE® communication protocols.
- Reading distance with ISO 14443A/MIFARE® cards can reach up to 50mm, depending on antenna tuning and size.
- Supports high-speed communication at 212 kbit/s and 424 kbit/s.
- Compatible with MIFARE® Classic encryption.
- 64-byte FIFO buffer for sending and receiving data.
- Flexible interrupt modes and programmable timer.
- Three power-saving modes: hardware power-down, software power-down, and transmitter power-down (which turns off the internal antenna driver).
- Built-in temperature sensor that automatically stops RF transmission if the chip overheats.
- Multiple independent power supplies prevent interference between modules and enhance stability.
- CRC and parity check functions; 16-bit CRC polynomial conforms to ISO/IEC 14443 and CCITT protocols.
- Internal oscillator with 27.12 MHz crystal.
