Customer Questions & Answers
What components are included in the RC522 module box and what are its physical dimensions?
The standard package includes the RC522 module, an integrated antenna, an RFID tag (key fob), a proximity card and male pins for connection. The module dimensions are 40 mm x 60 mm x approximately 5 mm in height.
What compatibility does the RC522 module have with microcontrollers and what are its electrical requirements?
The RC522 module is compatible with Arduino, Raspberry Pi and other microcontrollers with an SPI (Serial Peripheral Interface) interface. It requires a 3.3 V DC supply with a typical consumption between 13 mA and 26 mA during normal operation. It is not recommended to power the module directly at 5 V, as it may be damaged.
What communication protocols does the RC522 support and what are the common connection issues?
The RC522 communicates mainly via SPI, although it can be adapted to other protocols through modifications. The most common issues include errors caused by connecting it to 5 V, cables longer than 25 cm causing signal noise, and incorrect SPI pin configuration on the host. It is essential to use short cables and respect the power polarity.
What safety and regulatory considerations does the RC522 meet when used in access control applications?
The RC522 implements CRYPTO1 encryption for managing data with MIFARE cards, but this algorithm is vulnerable to known attacks, so it is not recommended for high-security applications. The module complies with ISO/IEC 14443A and operates in the 13.56 MHz ISM band, subject to local electromagnetic emissions regulations.
Is the RC522 Module compatible with Arduino boards?
Yes, the RC522 Module is fully compatible with Arduino boards via the SPI interface to make communication and project development easier.
What type of RFID cards does this module support?
It supports S50, S70, Ultralight, Pro and DESFire RFID cards at 13.56MHz.
What is the operating voltage of the RC522 Module?
The module operates at 3.3V DC.
What is included in the package when buying the RC522 Module?
The package includes the RFID-RC522 module, a blank standard S50 IC card, a special key fob-shaped card and a straight and angled pin header for connection.
What is the maximum data transfer speed?
The maximum data transfer speed is up to 10Mbit/s via the SPI interface.
