RFID Module Features
Being developed based on NXP's transponder IC, HF RFID Module is a Mifare read/write module. It supports Mifare 1K, Mifare 4K and Ultralight and is applicable for 13.56MHz. It does auto Real-time detecting tag which moves into or out of detective range and reports through one output pin's logic level. In addition, it integrates all necessary components and antenna into one PCB. The external Micro-controller can work with Module to read/write Mifare cards by simple serial communication command.
• Tag supported: Mifare 1K, Mifare 4K, Mifare UltraLight
• Auto finding cards.
• Built-in antenna.
• TTL UART interface
• Power supply: DC4.5V ~ 5.5V
• Operating distance: Up to 80mm, depending on tag
• Storage temperature: -40 ?C ~ +85 ?C
• Operating temperature: -20 ?C ~ +70 ?C
• Size: 80 ? 55 ?7 mm.
• Two LED, green led is auto light when card in, red led is controlled by host.
• The Card Status pin is low level indicating card in, and high level indicating card.
