Note: These modules are indiscriminate and will receive a fair amount of noise. Both the transmitter and receiver work at common frequencies and don’t have IDs. Therefore, a method of filtering this noise and pairing transmitter and receiver will be necessary. The example code below shows such an example for basic operation.

These wireless receivers work with our 315MHz transmitters. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. 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.
Note: These receivers are almost identical to the RF link 434MHz receiver. SparkFun does everything in our power to make sure you receive the product you requested. 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.
