NEW PART RC522 Mini RFID IC card reader module Small size 13.56MHZ RC 522 MODUL CARD SMART HOME

RC522 Mini RFID IC card reader module Small size 13.56MHZ
MFRC522 is a highly integrated card reader/writer chip used in 13.56MHz contactless communication. It is a low-voltage, low-cost, small-volume contactless card reader/writer chip launched for "three-meter" applications. It is a good choice for the development of smart meters and portable handheld devices. MFRC522 uses advanced modulation and decoding concepts to fully integrate all types of passive contactless communication methods and protocols at 13.56MHz. Supports 14443A compatible transponder signals. The digital part processes ISO14443A frames and error detection. In addition, it also supports the fast CRYPTO1 encryption algorithm to verify the MIFARE series products. MFRC522 supports higher-speed contactless communication of the MIFARE series, with a two-way data transmission rate of up to 424kbit/s. As a new member of the 13.56MHz high-integration card reader and writer series chip family, MF RC522 has many similarities with MF RC500 and MF RC530, but also has many characteristics and differences. It uses SPI mode to communicate with the host, which is conducive to reducing wiring and reducing the size of the PCB board. The MF522-MINI module uses the RC522 chip to design the card reader circuit. It currently works at a frequency of 13.56MHz and complies with the ISO14443A standard. It can support Mifare1 S50, Mifare1 $70, Mifare Light, Mifare Ultralight, and Mifare Pro. It is suitable for users who develop equipment, develop card readers, and design/produce RFID card terminals. This module can be directly loaded into various card reader molds. The module uses a voltage of 3.3V. Through a few simple lines of the SPI interface, it can be directly connected to any CPU motherboard of the user to communicate, which can ensure the stable and reliable operation of the module and the long card reading distance. The module is easy to use, highly reliable, and small in size, which can help customers apply contactless cards to the system conveniently and quickly.
