Sparkfun RF Link Receiver - 4800bps (434MHz)

The RF Link Receiver - 4800bps (434MHz) is a wireless receiver that pairs seamlessly with 434MHz transmitters. This compact device can be conveniently integrated into a breadboard and combined with microcontrollers to establish a simple wireless data link. However, these units are receivers only, implying that they can only facilitate one-way data communication. For two-way communication, you would require two pairs operating on different frequencies to function as a transmitter/receiver pair.One crucial aspect to note about these modules is their indiscriminate nature, which means they can pick up a considerable amount of noise. Given that both the transmitter and receiver operate at common frequencies and lack IDs, it is necessary to devise a method to filter this noise and pair the transmitter and receiver. An example code is provided for basic operation, and further resources can be found below for creating a reliable wireless data link.These receivers bear a striking resemblance to the RF link 315MHz receiver. SparkFun ensures that you receive the exact product you requested. However, if you suspect that you may have received the wrong product, you can verify which version receiver this is by conducting a simple test circuit.The RF Link Receiver boasts a range of features, including a frequency of 434MHz, a range of approximately 152 meters (under optimal conditions), a data rate of 4800bps, and a supply voltage of 5V.Several documents are available to assist users in getting the most out of their RF Link Receiver. These resources include an Arduino Library, a datasheet, a KLP Walkthrough Tutorial, a useful AVR Tutorial, and a GitHub link.
