Keyestudio MFRC522 RFID S50 Fudan card IC Card module with SPI port for Arduino UNO R3 MEGA 2560 R3

This Keyestudio MFRC522 RFID module is an affordable and easy-to-use reader/writer designed for students, educators, and makers working with contactless card systems. Operating at 13.56MHz, it is highly compatible with Arduino UNO R3, MEGA 2560, and other common microcontroller boards. It is perfect for developing access control systems, security projects, and interactive installations.

Original Philips MFRC522 chip

The module features the reliable Philips MFRC522 reader circuit chip, offering a low-cost and highly efficient solution for RF card development. It is designed to fit directly into a variety of reader moulds for seamless integration.

Simple SPI interface

This module operates on a 3.3V supply voltage and connects directly to any host CPU board. Using a simple SPI interface, you can establish communication with just a few wires, making it ideal for quick prototyping.

Broad card compatibility

The reader supports a wide range of standard contactless cards and transponders. It is fully compatible with mifare1 S50, mifare1 S70, mifare UltraLight, mifare Pro, and mifare Desfire card types.

Low power consumption

Designed for efficiency, the module has an active current draw of 13 to 26mA at 3.3V DC, which drops to an idle current of just 10 to 13mA. This low power footprint makes it suitable for battery-powered applications.

Versatile development options

The module is highly versatile and comes with comprehensive Wiki tutorials and Arduino software support. This ensures a smooth setup process for both beginners and advanced makers.

Industrial temperature tolerance

Built to handle diverse environments, the module operates reliably in temperatures ranging from -20 to +80 degrees Celsius. It can be stored safely in conditions from -40 to +85 degrees Celsius with relative humidity up to 95%.
