Safety Instructions
ESD Warnings
Electrostatic Discharges (ESD)
A sudden electrostatic discharge can destroy sensitive components. Proper packaging and earthing rules
must therefore be observed. Always take the following precautions.
•Transport boards and cards in electrostatically secure containers or bags.
•Keep electrostatically sensitive components in their containers, until they arrive at an
electrostatically protected workplace.
•Only touch electrostatically sensitive components when you are properly earthed.
•Store electrostatically sensitive components in protective packaging or on anti-static mats.
Grounding Methods
The following measures help to avoid electrostatic damages to the device:
•Cover workstations with approved antistatic material. Always wear a wrist strap connected to
workplace as well as properly grounded tools and equipment.
•Use antistatic mats, heel straps, or air ionizers for more protection.
•Always handle electrostatically sensitive components by their edge or by their casing.
•Avoid contact with pins, leads, or circuitry.
•Turn off power and input signals before inserting and removing connectors or connecting test
equipment.
•Keep work area free of non-conductive materials such as ordinary plastic assembly aids and
Styrofoam.
•Use field service tools such as cutters, screwdrivers, and vacuum cleaners which are conductive.
•Always place drives and boards PCB-assembly-side down on the foam.

Introduction
The SBC-R9 is an application-ready platform for your next product design. The system is based on the
200MHz Atmel AT91SAM9263 microcontroller boasting a 32-bit ARM® instruction set for maximum
performance. With up to 256MB RAM and 256MB NAND Flash memory, the unmatched I/O features of the
SBC-R9 extend the possible uses beyond traditional ARM applications.
To provide the fastest time to market, the Windows CE 6.0 BSP binary and low-level drivers for system I/O
are included. Additionally, the SBC-R9 software package is equipped with the Sealevel Talos I/O Framework,
which offers a high-level object-oriented .NET Compact Framework (CF) device interface. This interface
provides an I/O point abstraction layer with built-in support for the specific needs of analog and digital I/O
such as gain control and debouncing.
