Sparkfun Item #: WRL-13001 -

This is the HackRF One, a Software Defined Radio (SDR) peripheral capable of transmission or reception of radio signals from 1MHz to 6GHz. Designed to enable test and development of modern and next generation radio technologies, HackRF One is an open source hardware platform that can be used as a USB peripheral or programmed for stand-alone operation. If you are wondering what a SDR actually is, it's OK we can help. A Software Defined Radio is essentially a radio communication device that...

RF Link Receiver - 4800bps (315MHz)
Price: $11.25

Availability: Out of Stock
Sparkfun Item #: WRL-10533 -

These wireless receivers work with our 315MHz transmitters. They can easily fit into a breadboard and work well with microcontrollers to create a very simple wireless data link. Since these are only receivers, 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...
