This is a project from [Mirel] who built the system around a Arduino Mega 2560 and antipodal Vivaldi antennas, a type of directional antenna.

Some of the parts you will require include an Arduino Mega 2560, 2.4 inch TFT touch Screen LCD with inbuilt SD Card Slot, 4GB MicroSDHC, 20 Pin ZIF Socket and others.

It's of course backwards compatible with existing Arduino add-ons, but sets itself apart with a new USB controller with lower latency and driver-free operation on Mac and Linux.
