Introduction

1. Introduction
The Panel-Card is intended to be used as a small and medium size "intelligent" display
module as well as a universal Linux CPU card. It can be used where restricted energy
and space requirements play a role. It comes in different sizes and variations, but the
connector keeps the same, likewise the center of the LCD/TFT. Thus one baseboard can
carry different Panel-Cards, easily adopting to different needs.
The Panel-Card has all the necessary interfaces to support a huge variety of peripheral
devices. Dispensing with a parallel bus keeps the pin count small and makes it possible
to use rugged, inexpensive standard connectors.
The ARM architecture as a modern and widely supported processor architecture is
currently the platform of choice for medium performance embedded devices. Almost all
major processor manufacturers have ARM products in their portfolio.
The availability of the widespread operating system "Linux" for the ARM platform opens
access to a broad range of software, including tools, drivers, and software libraries.
Programs written for ARM can easily be employed on the PC platform for testing and
debugging.
Examples of actual or potential applications are: terminals, measuring and test equipment,
data-logging, as well as any simple or more complex control and automation tasks.

2. Scope
This document covers the following Panel-Card's:
• Panel-Card 35 TFT 320x240 transmissive
• Panel-Card 57 TFT 320x240
• Panel-Card 57 TFT 640x480
• Panel-Card 70 TFT 800x480
This document describes the most important hardware features of the Panel-Card. It
includes all informations necessary to develop a customer specific hardware for the Panel-
Card. The Operating System Linux is described in a further document.
The manual comprises only a brief description of the AT91SAM9261 processor, as this is
already described in depth in the manual of the manufacturer Atmel. Descriptions of the
ARM core ARM926EJ‑S are available from Atmel and also at http://www.arm.com. It is
much recommended to have a look at these documents for a thorough understanding of
the processor and its integrated peripherals.
The datasheet of the Ethernet controller is available at http://www.davicom.com.tw.
