RC522 Mini RFID Reader Writer Module 13.56MHz

The RC522 Mini RFID Radio Frequency IC Card Reader/Writer Module is an ultra-compact, high-performance contactless communication module operating at the 13.56MHz frequency. Based on the highly reliable MFRC522 chip, this mini-sized board is designed for low-voltage, low-cost, and extremely space-constrained applications. It provides a seamless way to integrate RFID card reading and writing capabilities into your custom embedded systems, smart locks, and security setups.

This module communicates with host microcontrollers via a high-speed SPI (Serial Peripheral Interface) bus, making it fully compatible with popular platforms like Arduino, ESP32, ESP8266, Raspberry Pi, and STM32. Whether you are designing an automated student attendance system, an inventory tracking device, or an IoT-enabled smart access control system, this lightweight and power-efficient module is the perfect fit for makers and professional engineers alike.

Features:

• Ultra-Compact Design: Extremely small footprint makes it ideal for portable devices and tight enclosures.
• High-Speed SPI Interface: Supports fast data transfer rates up to 10Mbit/s for rapid card detection.
• Low Power Consumption: Highly efficient active current and ultra-low sleep mode current extend battery life in remote projects.
• Contactless Communication: Operates at 13.56MHz, supporting Mifare1 S50, Mifare1 S70, Mifare UltraLight, and Mifare Pro cards.
• Wide Compatibility: Easily interfaces with 3.3V logic microcontrollers and features standard breadboard-friendly pin spacing.
