These Simple RF receivers are the easiest way possible to add wireless control, painlessly! There's no programming, configuring or addressing - simply power the receiver with 5-10VDC and press the buttons on our matching RF keyfob remote. When the A button is pressed, it activates the first pin, when the B button is pressed, it activates the second one, and so forth for all four buttons. There's no microcontroller required, its just a simple one-to-one link.

This 4-button keyfob remote goes with our three basic 315MHz RF receiver modules. It will work with all of them, sending out one of four commands that match up with the four outputs. Its small and light weight and will work up to 25 feet away depending on line-of-sight and obstructions. Since this is just a transmitter, if you have multiple receivers, it will turn all of them on and off at the same time (there is no sub-addressing).
