• Broad Microcontroller Compatibility: Seamlessly integrates with Arduino, ESP32, and Raspberry Pi platforms, ensuring flexibility for various development projects.

• I2C Communication: 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.

• 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.

• 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.

Brief introduction

1. RFID chip design for card reading circuits is convenient to use, cost-effective, and suitable for advanced applications such as device development and card reader development, as well as users who need to design/produce RF card terminals.

2. The module can automatically read the ID card number of the IC card (that is, if the IC card is close when powered on, the ID card number in hexadecimal can be automatically read, and the card number is issued through the serial port without the need for commands).
