This compact 4-button keyfob transmitter operates on 315 MHz and is designed to work with compatible 315 MHz RF receiver modules. Each button sends a distinct command corresponding to four output channels, making it suitable for simple remote control applications.

The keyfob is small and lightweight with a range of approximately 7.5 metres (25 ft) depending on line of sight and obstructions. As a transmitter-only device, it will activate all paired receivers simultaneously — there is no sub-addressing for individual receiver control.
