RC522 13.56MHz RFID Mini Reader Module + Card + Key Fob - Arduino

Miniature version of well-known RFID contactless access control module. It enables the construction of alarm systems, access system, employee time control, etc. Perfect for uC AVR, Arduino, PIC, and other systems. Ready libraries for the Arduino IDE facilitate the operation and the speed of creating the system. Product Features The Rfid RC522 module is a highly integrated chip for reading and writing (13.56MH) contactless cards Module easy to use, cheap, and apply to user equipment development, reader and advanced application development, the need for RF user card terminal design / production. The module supports the CRYPTO1 high-speed encryption algorithm, Mifare products terminology validation. The module uses a voltage of 3.3V Communication via the SPI interface using simple commands Working range - up to 10mm Technical data Working current: 13-26mA Supply voltage: 3.3V Idle Current: 10-13mA Sleep current: below 80uA SPI interfaces Module Parameter Data transfer rate: maximum 10Mbit / s Supported card types: mifare1 S50, S70 Mifare Ultralight Mifare1 Mifare Pro MIFARE DESFire

Module size: 37.5mm*25.1mm Our expert advises The module is a clone, which can be seen from the text on the product as RFIO, not RFID, in addition, its SPI bus address is 0x88 and not 0x92. This is manifested by changes in the antenna arrangement, where the capacitors should be placed in a different order. You should replace the capacitors C6 with C8 and C11 with C9 so that C6, C7, C10 and C11 have a capacity of 15 pF, while C8 and C9 180pF, this procedure will restore a greater range of reading cards and key fobs.
