Description

***** JMY**1G is a RFID read/write module with an UART and IIC serial port. The module supports ISO/IEC****3 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 CL RC**0 Working frequency:*3.*6MHz Card supported:TI TagIt, NXP ***** SLI, ST LRI and other ISO****3 tags 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 ON 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:**4 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. And IIC is able to connect with **8 devices. We have detailed sample source code for users. 5.Automatic Detecting card Automatic detecting card support all function of ISO****3. Automatic detecting card support only one card operation. We have KELL project in C*1 and ASM*1 format to help users. If need user manual or any helps, feel free to contact us.
