6 Mechanical description
The Atmel REB231FE2 is manufactured using a low-cost, two-layer printed circuit
board. All components and connectors are mounted on the top side of the board.
The format was defined to fit the EXPAND1 connector on the REB-CBB and Atmel
AVR STK500 / STK501 microcontroller evaluation board. The upright position is
chosen for best antenna performance.
