![]() However, if you are concerned you may have received the incorrect product you can verify which version receiver this is by running a simple test circuit. ![]() SparkFun does everything in our power to make sure you receive the product you requested. Note: These receivers are almost identical to the RF link 315MHz receiver. Please refer to the example code and links below for ways to accomplish a robust wireless data link. ![]() The example code below shows such an example for basic operation. Therefore, a method of filtering this noise and pairing transmitter and receiver will be necessary. Both the transmitter and receiver work at common frequencies and don't have IDs. Note: These modules are indiscriminate and will receive a fair amount of noise. Since these are only receivers, they will only work communicating data one-way, you would need two pairs (of different frequencies) to act as a transmitter/receiver pair. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. These wireless receivers work with our 434MHz transmitters.
