The reference layout for this device is available through support@rfdigital.com if you want to build it yourself. However if you wish to purchase the ready-made KEYFOBs from RF Digital they are available, part numbers shown below. There are two modes of use, one is in Active RFID mode were the KEYFOB automatically transmits its ESN once every 30 seconds. The other mode of use is SWITCH transmitter, which is available in 1, 2 or 3 buttons. The RFID versions also have 1, 2 or 3 buttons so they serve as an automatic RFID transmitter and in addition have the switch buttons in one KEYFOB. If you do not need the automatic Active RFID feature, just use the Switch Button KEYFOBs. KEYFOBs Pressing button 1, 2 or 3 will cause the output 1, 2 or 3 on the RFD21733 Module or RFD21743 / RFD21732 RFDANT to go high for the duration the button is pressed, when in one of the 4 switch modes. If in Serial UART mode, then you will receive 1 byte representing which button is pressed or if RFID transmission and 4 more bytes indicating the 32 bit unique ESN of the KEYFOB. Rotatable Buttons RFD21783 3 Button RFID Keyfob 3 Button Switch Keyfob RFD21793 Pressing button 1 or 3 will cause the output 1 or 3 on the RFD21733 Module or RFD21743 / RFD21732 RFDANT to go high for the duration the button is pressed, when in one of the 4 switch modes. If in Serial UART mode, then you will receive 1 byte representing which button is pressed or if RFID transmission and 4 more bytes indicating the 32 bit unique ESN of the KEYFOB. Rotatable Buttons RFD21782 2 Button RFID Keyfob 2 Button Switch Keyfob RFD21792 Pressing button 2 will cause the output 2 on the RFD21733 Module or RFD21743 / RFD21732 RFDANT to go high for the duration the button is pressed, when in one of the 4 switch modes. If in Serial UART mode, then you will receive 1 byte representing which button is pressed or if RFID transmission and 4 more bytes indicating the 32 bit unique ESN of the KEYFOB.
