These are wireless transmitters which work on the 434MHz frequency. Use these components to transmit position data, temperature data, and even current program register values wirelessly to the receiver. 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.

Please 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 shows such an example for basic operation. Please refer to the example code and links below for ways to accomplish a robust wireless data link.
  • We also stock the RF Link Receiver - 4800bps (434MHz).
