RFID touchless access control module. It allows you to build alarm systems, access system, etc. Ideal do uC AVR, Arduino, PIC, and others. The module supports the CRYPTO1 fast encryption algorithm in Mifare product terminology. The Rfid RC522 module is a highly integrated do read and write (13,56MH) contactless card chip The module is easy to use, cheap, and applies do the development of user equipment, reader and advanced application development, the need to design RF user/production card terminals. The module supports CRYPTO1 fast encryption algorithm, Mifare product terminology. The module uses a voltage of 3.3V Communication via SPI interface using simple commands Working range - do 40mm Technical data: Operating 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 Dimensions: 40x60mm Included: RC522 reader Card Pendant Pins do soldering Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
