Connection Diagram
The representation below shows a typical interface to the Key Fob Receiver Board. Resistors indicate your
added devices (e.g. microcontroller I/O pin, relay, etc…).
Receiver Board
The receiver board only needs 5 VDC on the VCC pin. Once it is powered up, you are ready to connect
“VT” or any of the “D” pins to your project.
The Receiver Board has a pre-soldered antenna in “ANT2”. You can uncoil the antenna to help increase
the range. Maximum range is ~250 feet line-of-sight. To add even more range to the receiver you can
add your own antenna to “ANT1” on the receiver board.
