RF Digital RFD21815 Open Source Wireless Inventors Shield for Arduino allows a wireless connection between two Arduino boards to be set up quickly and reliably with a distance of 500ft. The inventors shield uses a wireless pipe, which is a special wireless RF module that allows the user to easily and reliably send and receive error-free wireless data between two or more Arduino boards. RFD21815 is ready to use out of the box, and does not require any complicated channel selection, setup, or initialization. The shield has a long range for distances up to 500ft, and also offers built-in forward error correction and data recovery. It is immune to noise so that 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 a wireless project in its tracks are no longer an issue with the RFD21815 Wireless Inventors Shield.
