RFID Module – RC522, 13.56MHz, I2C Protocol, Compatible with Arduino, ESP32, Raspberry Pi, Supports Automatic Card/Data Reading, with Ph2.0 to Dupont Cable & Blank White Card

About this item

• Broad Microcontroller Compatibility: Seamlessly integrates with Arduino, ESP32, and Raspberry Pi platforms, ensuring flexibility for various development projects. Docs: github.com/nulllaborg/rfid
• Flexible Automatic Reading Modes: Features three user-selectable automatic reading modes: Automatic Card ID (UID) Reading, Automatic Block Data Reading, and a Combined Reading Mode, streamlining data acquisition from RF media.
• Standard High Frequency Operation: Operates at the industry-standard frequency of 13.56MHz, and is compatible with various RF media types, including RFID tags, key fobs, coin cards, and standard white cards.
• Low-Power I2C Communication: Utilizes the efficient I2C protocol, address 0x28, simplifying wiring and reducing pin count. The module features low power consumption with a sleep current of <80uA and a typical operating voltage of 5V.
• Compact and Efficient Design: size (56mm x 40mm), making it ideal for space-constrained projects. Its peak current is limited to <100mA, ensuring reliable and safe operation.
