Presented below is a simple and cheap 433-Mz RF Sniffer ideal for testing/reverse-engineering most 433-MHz wireless devices. As you can see, the setup is on the Arduino ground with a 433-MHz receiver ...

which are all controlled via a single SPI bus with an Arduino. Each RF switch is activated in a pseudo-random sequence, changing the configuration of the panel 10,000 times in 100 ms. The signal ...

What do you get when you combine a direct digital synthesis (DDS) chip, a power detector, and an Arduino? [Brett Killion] did make that combination and wound up with a practical network analyzer.

Lime CEO and Myriad-RF creator. “We’re trying to create an Arduino for the RF sector; a board that’s low cost, powerful, exceptionally flexible and easy to use. And, most importantly, we’re trying to ...

Makers, hobbyists and developers looking for a low powered Arduino compatible development board with built-in RF capable of running AVR projects for years using just a single AA battery.

Move-X is aiming at tracking applications that need meter-level accuracy and a long-range battery-powered wireless connection with a module that is physically compatible with Arduino’s 63mm long MKR ...
