Big Performance in a Tiny Footprint: The RC522 Mini

For developers and hobbyists building the next generation of IoT devices or secure access systems, space is often a luxury. The RC522 Mini Version RFID Module solves the bulk issue of traditional readers. Engineered with the robust NXP MFRC522 chip, this module delivers reliable Near Field Communication (NFC) and RFID capabilities in a form factor nearly half the size of standard boards.

Seamless Embedded Integration

Whether you are prototyping a smart drawer lock with an Arduino Nano or building a complex attendance system with an STM32, this module is designed for versatility. It operates on the highly stable 13.56MHz band (ISO/IEC 14443A standard), ensuring compatibility with widely available MIFARE Classic 1K cards and tags.

Why Choose the Mini Version?

• Space-Saving Design: At approximately 25mm x 37mm, it fits into enclosures where standard readers cannot.
• Stable Communication: Utilizing the SPI interface ensures high-speed data transfer (10Mbit/s} max), crucial for quick card scanning and authentication processes.
• Low Power Consumption: Optimized for battery-operated portable devices, drawing minimal current during standby.

Ready for STEM & DIY

At Sun Cheong Computer, we recommend this module for STEM education and DIY electronics. It allows students and makers to understand the fundamentals of Radio Frequency Identification (RFID) through hands-on coding. The kit comes complete with headers, a blank S50 card, and a keychain tag, so you can start coding immediately.
