RF Link Transmitter - 434MHz

Sparkfun's RF Link Transmitter operates at 434MHz and is designed to work seamlessly with 434MHz receivers. This compact wireless transmitter is breadboard-friendly and pairs effectively with microcontrollers to establish a simple, one-way wireless data link. However, it's worth noting that for two-way communication, you'd require two sets of transmitters and receivers operating at different frequencies.

Although the RF Link Transmitter operates at common frequencies and doesn't possess unique IDs, it may receive a significant amount of noise. Therefore, it's essential to develop a method for filtering out this noise and pairing the transmitter and receiver effectively. Some example code is available to demonstrate the basics of operation and provide guidance on establishing a robust wireless data link.

The color of the module may vary between blue and green, but regardless of color, the functionality remains the same.

Key features of the RF Link Transmitter include a 434 MHz operating frequency, a range of up to 152.4 meters (under optimal conditions), a data rate of 4800bps, and a supply voltage of 5V.

For further information and technical details about the RF Link Transmitter, refer to the Arduino Library, Datasheet, KLP Walkthrough Tutorial, Good AVR Tutorial, and GitHub documents. These resources provide valuable insights into the product's capabilities and offer useful tutorials for setup and operation.

In summary, Sparkfun's RF Link Transmitter - 434MHz is a compact and efficient solution for establishing a simple, one-way wireless data link. Its compatibility with 434MHz receivers and microcontrollers makes it a versatile tool for a wide range of applications.
