Description

***** JMY**1A is a RFID read/write module with an UART and IIC serial port. The module supports ISO/IEC****3A contactless cards. The module has various functions. User operates the module via simple commands. The module has excellent performance and stability. The antenna is separated from the module. ***** PCD model: NXP MF RC**0 Working frequency:*3.*6MHz Card supported:Mifare 1K/4K, FM*1RF*8, Ultra Light, DesFire, Mifare ProX, T=CL smart cards(ISO****3A) Anti collision ability:Full function anti collision; be able to process multi-cards; be able to set operate single card only Auto detecting card:Supported, default OFF EEPROM:**2 Bytes Power supply:DC 5V (±0.5V) Interface:IIC & UART (selected by SPS pin, recommend to use IIC) Communication rate:IIC: **0Kbps UART: *9.2Kbps/**5.2Kbps Max. command length:**3 Bytes Interface level:3.3V (TTL level; 5V tolerance) Power consumption:*0mA Operating distance:**0mm (depending on card and antenna design) Dimension:*1mm * *2mm Package:DIP*2 Weight:About *5g ISP:Supported Operating temperature:**5 to **5 ℃ Storage temperature:**0 to ***5 ℃ RoHS:Supported 3.Antenna We supply the antennas. There are three models: TX**0, TX**1 and TX**2. The antenna customization is welcomed. 4.Protocol There are IIC and UART interface between the module and IIC. We recommend using IIC whose baud rate is **0Kbps. IIC is able to connect with **8 devices. We have detailed sample source code for users. 5.Automatic Detecting card Automatic detecting card supports full function of Mifare 1k/4k and ultra light. Automatic detecting card support only one card operation. We have KELL project for users, if need help, please mail to jinmuyu_trade2(a)*****
