Model: SM522T Working current: 13~26mA/DC 3.3V Idle current: 10-13mA/DC 3.3V Peak current: <30mA Working frequency: 13.56MHz Protocol standard: ISO 14443 TypeA Support card: Mifare 1K S50, Mifare 4K S70 (4 bytes ID number) Read distance: 5cm Interface: UART TTL Data transfer rate: max.10Mbit/s Card reading speed: read ID number 7 times per second, read data block 3 times per second Size: 31.5mm×50mm Working environment temperature: -20℃~+80℃ Storage temperature: -40℃~+85℃ Relative humidity: 5%~95%
MF RC522 Write/Read Module have own CPU control, without written protocol, the device via a serial port connection module immediately. Module fully serial port control (USB/Ethernet turn serial port), without complex SPI, any platform system seamlessly, compatible with any system with the serial port (51 Microcontroller, ARM, Linux, Arduino, Windows, etc.) Only in accordance with the simple command, RFID module can easily operate the IC card reading, writing, add and subtract values (but not modify the IC card ID number) Module automatically read the IC card ID number ((when energized, the IC card is near, IC card read automatically hexadecimal ID number, ID number issued via a serial port, need not send command) Modules have multiple instruction and single instruction to read and write functions at the same time, the user can through an instruction is complete to read or write operation.
