RF Digital RFduino RFD21815 Open Source Wireless Inventors Shield for Arduino uses a wireless pipe, which is a special wireless RF module that allows you to easily and reliably, send and receive error-free wireless data between two or more Arduino boards. The inventors shield “Just Works”, no complicated channels to select, to setup or initialization. Just plug it in and its ready to go. No extra libraries are required.
It's Long Range - distances up to 500 feet.
It's Error Free - built-in forward error correction and data recovery, you only ever receive cleaned and CRC verified data.
It's Simple To Use - anything you input, is wirelessly transmitted, then cleanly outputted for you on the other end. Compatible with the Arduino serial and software serial library.
It's Immune To Noise - your data inside the wireless pipe is protected from the elements outside such as interferences like WiFi, Bluetooth, Zigbee, cordless phones, cellular phones, all types of servo and motor noise, etc. All things which typically stop your wireless project in its tracks, are no longer an issue.
