The RFID-RC522 is a compact module designed for reading and writing RFID cards, commonly used in DIY electronics and security projects. It operates at a standard 13.56MHz frequency, making it suitable for interfacing with various microcontrollers for tasks like access control or data logging.
In everyday use, this module can help enthusiasts build simple security systems, such as key fob readers for home entry or inventory tracking in small-scale applications. It integrates easily into Arduino or similar setups, allowing users to detect and process RFID tags without complex wiring.
- Supports Mifare1 S50, S70, Ultralight, Pro, and Desfare cards for versatile compatibility
- Low working current of 13-26mA at 3.3V, ideal for battery-powered devices
- Idle current as low as 10-13mA and sleep mode under 80uA for energy efficiency
- Peak current stays below 30mA, preventing overload in sensitive circuits
- 13.56MHz frequency ensures reliable performance in standard RFID applications
Light specifications include a compact design that fits into most prototyping boards. This module is a practical choice for hobbyists and developers working on electronic projects requiring RFID functionality.
