The RF Transmitter Receiver Module can easily fit into a breadboard and work well with microcontrollers to create a very simple wireleReceiving frequency (MHz)ss 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. This wireless transmitter and receiver pair operate at 315Mhz. 

This Radio Transmitter & Receiver pair is perfectly matched to allow you to control items from a distance up to 500 feet wirelessly! Connect the transmitter to your Arduino, Raspberry Pi, or other microcontroller and the receiver to whatever you’d like to control. Both the transmitter and receiver are in tune with the same Radio Frequency so that when the transmitter emits a signal, the receiver will hear it wirelessly. This Module 315MHz Wireless Link Kit is great for easy and simple wireless control! Arduino & Raspberry Pi 2 / B / B+ / A+ Compatible!

Great product, just one "issue".

So far so good! They communicate pretty effectively at a decent distance. Only issue I had was with getting the right frequency for the receiver. It wasn't calibrated at the factory. To those that are struggling: hook the pair up to some Arduinos and have one constantly transmit a signal, on the receiving end, just continually scan for that signal and slowly turn the frequency knob until you pick it up. Best wishes! Stay creative.

... dozens of these over the years and they work great!

I have purchased dozens of these over the years and they work great!

Transmitter and Receiver works like a charm

Transmitter and Receiver works like a charm.Only request from the manufacturer is to label the frequency on the Receiver piece.

Does what it does

It takes the air and makes it 315mhz bits instead. It did this with modest efficacy.Clearly recycled parts which is good.Probably made with slave labor. :-(
