The Sparkfun RF Link Receiver - 4800bps (315MHz) is a wireless receiver that is compatible with 315MHz transmitters. It is compact and can seamlessly integrate into a breadboard, making it ideal for use with microcontrollers to establish a straightforward wireless data link. However, as these are solely receivers, they can only facilitate one-way data communication. For two-way data transmission, you would need two sets of receivers and transmitters operating at different frequencies.
Please note that these modules can pick up a considerable amount of noise as both the transmitter and receiver operate at common frequencies and lack identification. Hence, a method to filter this noise and pair the transmitter with the receiver will be necessary. For basic operation, refer to the example code provided.
These receivers are nearly identical to the RF link 434MHz receiver by Sparkfun. If you have concerns about receiving the wrong product, you can verify the receiver version by running a simple test circuit.
Key features of the Sparkfun RF Link Receiver - 4800bps (315MHz) include:
- Operating frequency of 315 MHz
- Range of up to 152.4 meters under optimal conditions
- Data rate of 4800bps
- Requires a 5V supply voltage
