• Inventory management
• Asset tracking
• DIY electronics projects

Usage:

1. Wiring:
   • Connect the RC522 RFID module to your microcontroller platform using SPI, I2C, or UART interfaces. For Arduino, the typical SPI connections are:
     • VCC to 3.3V
     • GND to GND
     • RST to Pin 9
     • IRQ (not used)
     • MISO to Pin 12
     • MOSI to Pin 11
     • SCK to Pin 13
     • SDA (SS) to Pin 10
2. Programming:
   • Install the necessary libraries (e.g., MFRC522 library for Arduino).
   • Use example code to initialize the module and read RFID tags or cards.

3. Testing:

1. • Present an RFID card or key fob to the module and observe the UID output on the serial monitor.

Caution:

• Ensure proper handling to avoid damage from electrostatic discharge (ESD).
• Verify power supply requirements to prevent damage to the module.
• Keep the module away from strong electromagnetic fields to ensure reliable operation.
