ماژول RFID با قابلیت خواندن نوشتن فرکانس 13.56MHZ ورژن V5 Ultralight

Introduction

We embeded an MCU on this module. By sending command via UART interface, you can make it work. Operation is very easy. Most work is done by the embededMCU. There is also a SPI interface on the board. This is the MFRC's SPI. You can access MFRC directly via this inteface.There are two kinds of command: Basic command and compact command. All the command are in Hex format. Please download manual for more information. Connecting with Arduino is pretty easy. With Arduino Sensor Shield, just plug in and play.

Specification

Highly integrated analog circuitry to demodulate and decode responses

Supports ISO/IEC14443A/MIFARE

Typical operating distance in Reader/Writer mode for communication to a ISO/IEC14443A / MIFARE is 40~50 mm

Supports MIFARE Classic encryption in Reader/Writer mode

Supports ISO/IEC14443A higher transfer speed communication up to 848kbit/s

Control by Serial UART interface: Baud rate could be 2400bps ~ 115200bps, with default baud rate 9600bps

With the chip ISO14443, it supports MIFARE standard encryption algorithm

Configuration data is preserved in EEPROM against power cut off

Built-in 8K EEPROM, easy to access it by sending commands

Easy to use, by sending simple commands users can control it to read or write cards

In compact command, command is as short as one byte

Excellent EMC performance
