Section 3

Setting Up the AT91EB01 Evaluation

Board

3.1

Electrostatic 
Warning

The AT91EB01 Evaluation Board is shipped in protective packaging. The board must
not be subjected to high electrostatic potentials. A grounding strap or similar protective
device should be worn when handling the board. Avoid touching the component pins or
any other metallic element.

3.2

Requirements

Requirements in order to set up the AT91EB01 Evaluation Board are:

■

the host computer running the ARM Software Development Toolkit (a time-limited 
evaluation copy is provided with the Kit version of the AT91EB01)

■

the AT91EB01 Evaluation Board itself

■

suitable connection between the host and the development board (see the following 
sections)

■

DC power supply capable of supplying 7.5V to 9V @ 500 mA (not supplied)

3.3

Layout

Figure 3-1 shows the layout of the AT91EB01 evaluation board.
