KEYFOBs
The RFD21733 Module with its RFID interval factory set to 30 seconds is inside of a KEYFOB
enclosure with a CR2032 battery. 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.

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
