433MHz RF Transmitter - Receiver Module - (AD25256)

Description:

These wireless transmitters work with our 433MHz receivers. They can easily fit onto a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are transmitters only, they will only work communicating data in one direction; you would need two pairs (of different frequencies) to act as a transmitter/receiver pair.

Note: These modules are indiscriminate and will pick up a fair amount of noise. Both the transmitter and receiver operate on common frequencies and have no IDs. Therefore, a method will be necessary to filter out this noise and pair the transmitter and receiver. The following example code demonstrates an example of basic operation. Refer to the example code and links below for ways to achieve a robust wireless data link.
