3 Overview
The Atmel REB-CBB is designed to interface directly to a radio extender board. The
combination of the two boards form a battery powered, fully functional, portable
wireless node. The setup provides an ideal platform to:
• Evaluate the outstanding performance of the Atmel radio transceivers
• Test the unique radio transceiver hardware support for the
IEEE
®
802.15.4 standard [3]
• Test the enhanced radio transceiver feature set
• Develop applications capable of hosting a ZigBee
®
stack
The following table lists the available radio extender boards and related radio
transceivers.

Note: (1) Currently there exists no Evaluation Kit, but the plain radio extender
is purchasable from http://www.dresden-elektronik.de/shop/.
The REB-CBB is assembled with an Atmel 8-bit AVR ATxmega256A3 microcontroller.
It offers a connector for programming and debugging, suitable to connect an Atmel
JTAGICE mkII programmer. A connector to attach an asynchronous serial interface
allows interfacing to a PC host for control and data exchange tasks.
Figure 3-1 shows a development and evaluation setup using the REB-CBB in
combination with the REB231ED radio extender board.
