RC522 RFID Reader Module

RC522 chip
RC522 is applied to 13.56MHz contactless communication highly integrated chip card reader, is a low-voltage, low-cost, small size and non-contact card reader chip, smart instrumentation and portable handheld devices developed better choice.

RC522 using advanced modulation and demodulation concept completely integrated in all types of 13.56MHz passive contactless communication methods and protocols.

RFID module
This module can be loaded directly into a variety of readers molds. Module uses voltage of 3.3V, through the SPI interface simple few lines can be directly connected to the user any CPU board communication module can guarantee stable and reliable work, reader distance.
