SparkFun RF Link Transmitter - 315MHz General Tree Stands RS-485 input/output broken out toThese wireless transmitters work with our 315MHz receivers. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only transmitters, 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 modules are indiscriminate and will receive a fair amount of noise. Both the transmitter
