RDM6300 RFID reader<\/h2>\n
RFID stands for Radio Frequency Identification. It is a tagging identification system that uses electromagnetic waves in radio frequency to transfer data. An RFID system consists of a passive card or tag and an active read or write device which is RDM6300 in our case.<\/p>\n
RDM6300 RFID module is a low-cost RFID reader. You can purchase it for less than 5$ as compared to RDM630 which costs approximately $10-15. Both of the modules work on a 125kHz radio frequency. Therefore, they are able to detect RFID tags or cards which can communicate with RFID readers at 125KHz frequency. RDM6300 RFID module works on transistor logic or in short TTL logic. It means you need to provide 5 volt dc to power supply pins of this module. It has\u00a0a\u00a0UART communication<\/strong><\/a>\u00a0function. In other words, it can communicate with microcontroller through a UART serial communication.\u00a0 It has TTL RS232 format.<\/p>\n Note: RDM6300 can only read data from 125KHz tags or cards.<\/p>\n Below you can view the two RDM630 and RDM6300 modules:<\/p>\n The RDM6300 module consists of 10 pins out of which only 5 pins are required to interface this RFID tag reader with Arduino.\u00a0You can view the pinout below:<\/p>\n The RDM6300 module consists of three headers as shown above. Details of P1 header pins are given below:<\/p>\n The antenna is connected to the P2 header. Details of P2 header pins are given below:<\/p>\n\n
