1 Introduction
This application note describes the Atmel REB Controller Base Board (REB-CBB).
Detailed information about its functionality, its interfaces, the microcontroller
programming, and the PCB design is given in the individual sections.
The REB-CBB is intended to serve as a microcontroller platform for the Atmel
Radio Extender Board (REB) family. The REB connected to a REB-CBB forms a
battery powered, fully functional, and portable wireless node.
