RF Link Transmitter - 315MHz

The RF Link Transmitter - 315MHz by Sparkfun is a versatile wireless transmitter that operates in harmony with 315MHz receivers. It is designed to fit seamlessly into a breadboard and interfaces effectively with microcontrollers, facilitating a simplistic wireless data link. Please note that these are purely transmitters, hence they can only transmit data in one direction. For two-way communication, you would need two sets of transmitters and receivers with different frequencies.

It is important to note that these modules do not discriminate and can pick up a significant amount of noise. As both the transmitter and receiver operate at common frequencies and lack IDs, it is crucial to develop a method for filtering this noise and pairing the transmitter with its receiver. The basic operation can be understood by referring to the example code provided.

The RF Link Transmitter - 315MHz comes with a range of features that make it a standout choice for your wireless data link needs. It operates at 315MHz and can transmit data up to a distance of 152.4 meters (500 feet) under ideal conditions. It boasts a data rate of 4800bps and requires a supply voltage of 5V to function.

Sparkfun also provides a wealth of resources to help you get the most out of your RF Link Transmitter. These include an Arduino Library, a datasheet for the TWS-BS-6 model, a KLP Walkthrough Tutorial, a useful AVR Tutorial, and a GitHub repository. These resources provide comprehensive guidance on how to effectively use and integrate the RF Link Transmitter into your projects.
