SparkFun RF Link Transmitter - 434MHz GeneralThese wireless transmitters work with our 434MHz 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

These wireless transmitters work with our 434MHz 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 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. Please refer to the example code and links below for ways to accomplish a robust wireless data link.

Note: Color may be blue or green, but they are the same module.

Features:

  • 434 MHz
  • 500ft range (given perfect conditions)
  • 4800bps data rate
  • 5V supply voltage

With the word Trilogy, made me think I was getting all 3
Arrival was great and on time. Thought I was getting the timepiece the second in trilogy. But will keep it and order the other two of the series I typed in the name “Timepiece” and got The Christmas Box, thinking I was possibly getting all 3. I guess that is my mistake
