Description of DQ310

SUMMARY

DQ310, an IC cards read and write module designed by small size, low power check card (LPCD) and easy operation. This RFID module can read the main  part of smart cards.

The module and antenna is integrated.Easy to usesafety to opreate, It has various functions and terms multi ISO/IEC standard of contactless card.Widely used in office/home security, personal identity, entrance guard system, security systems, intelligent instruments and meters, interactive toys and production process control ,which a variety of wireless radio frequency identification (RFID) system.The PCB and antenna are connected by 50 ohm feeder, that convenient and easy to use.

ANTENNA DESIGN

We offer two standard size antennas, and the customer can customize the antenna according to the actual situation.

4.1   30mm*30mm Antenna

 

 

 

 

 

4.2 50mm*50mm  Antenna

 

 

 

 

LOW  POWER  CHECK  CARD

Keepping INT pin in high level or dangling situationModule is normal working

Using externalIOput INT pin in low power levelModule is working in LPCD situation

Putting the card in areas ofthe antennathe module’s INT pin keeps in high power level.

The upper detects high level ,then needs to pull the IO up, themodule comes to normal operation .
