Chapter 1. Preface

Thank you for purchasing the Armadillo-440 LCD Model Development Set.

The Armadillo-440 LCD Model Development Set is comprised of the "Armadillo-440" which as a CPU board pro-

vides the core functionality, and the "Armadillo-400 Series LCD Expansion Board" which incorporates LCD, touch

screen and audio functionality.

The Armadillo-440 is a small form factor general purpose CPU board which along with the Freescale ARM9 processor

"i.MX257", LPDDR SDRAM and flash memory, also incorporates interfaces which are often required for embedded de-

vices, such as serial, LAN, USB 2.0, microSD and GPIO. Armadillo-440 keeps pin compatibility with the existing Arma-

dillo-220 model while at the same time also offering improved performance and even lower power consumption.

The Armadillo-400 Series LCD Expansion Board is designed to be connected to the Armadillo-440 and incorporates

the functionality required to create a touch screen computer, including LCD and touch screen interfaces, audio in and out

and button input. As the circuit diagrams for the Armadillo-400 Series LCD Expansion board have been made available,

it is possible to quickly meet various hardware requirements when developing a panel computer by using Armadillo-440

as is and just customizing the expansion board.

Linux is employed as the standard operating system on Armadillo-440, providing access to a rich array of software

resources. It is also possible to create and run original programs with C and other programming languages. For informa-

tion on how to customize software, please refer to the "Armadillo-400 Series Software Manual."

This document contains precautions for use and explanations on how to use the software functionality available in the

default state as at time of purchase. On obtaining the Armadillo-440 LCD Model Development Set, please check the op-

eration of all hardware and the use of the default software.

The product name "Armadillo" will be used in descriptions that apply to the whole Armadillo Series for the remainder

of this document.
