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.

•Please do not use products with Wireless LAN functionality in places near
medical devices such as heart pacemakers and hearing aids, automatic control
equipment such as fire alarms and automatic doors, microwave ovens, ad-
vanced electronic equipment or televisions and radios, or near "Premises Ra-
dio Stations" for "Mobile Body Identification" or "Specified Low Power Ra-
dio Stations". The radio waves emitted by this product may cause these types
of devices to malfunction.
2.2. Handling Precautions
Please pay attention to the following points when handling this product in order to avoid causing any irreversible damage.
Areas Easily Damaged The microSD connector and its cover and the connectors of the flat cable from
Armadillo-440 and Armadillo-460 to the LCD Expansion Board can be easily
damaged. Please be careful not to damage them by handling them with too much
force.
Modifications To This Product Please take note that any modifications[1] made to this product are not covered
under warranty. Also, please ensure to undertake a full operational check of this
product before carrying out any modifications or mounting connectors[2].
Mounting and Dismounting of Con-
nectors While Powered On Apart from hot-pluggable interfaces (LAN, USB, SD, Mic, Headphone), do not under any circumstances insert or remove connectors while power is supplied to
this product or peripheral circuits.
Static Electricity As CMOS devices are used in this product, please store it in antistatic packaging
(such as that it was shipped in) until time of use.
Latchup Excessivenoiseorasurgefromthepowersupplyorinput/output,orsharpvoltage
fluctuations can lead to the CMOS devices incorporated in the board causing a
latch-up.Once the latch-up occurs,thissituation continues until the powersupply
is disconnected, and therefore can damage the devices. Measures such as adding
a protection circuit to noise-susceptible input/output lines or not sharing the
powersupplywithdevicesthatcanbethecauseofnoisearehighlyrecommended.
Physical Stress Please avoid strong physical stress such as drops or other impacts.
Touch Panel Operation The touch panel LCD module on the LCD expansion board is fixed with flexible
double sided tape. If a strong force is applied to the LCD screen the double sided
tape may give and the LCD frame may touch the board wiring. Please take care
not to push the LCD screen stronger than necessary.
2.3. Software Usage Precautions
About Software Contained In This
Product The software and documentation contained in this product is provided “AS IS”. The customer is required to assume the responsibility of only using this product
after having fully considered and tested its suitability to the intended purpose and
use. There is no guarantee of fitness for a particular purpose, reliability, correct-
ness and no guarantee of any outcomes resulting from the use of this product.
[1]With the exception of any methods of modification introduced in this and related product manuals, and the mounting of connectors to unmounted
interfaces.
[2]When making modifications or mounting connectors, please ensure to apply masking and avoid solder residue or solder balls coming in contact with
surrounding parts.

2.4. Write Prohibited Regions
The data stored by the EEPROM, CPLD and i.MX257 electrical fuse (e-Fuse) is
used by the software contained in this product. Please do not write to these regions
as the product may stop operating correctly. Purposefully writing to these regions
voids the product warranty.
2.5. Electromagnetic Interference
The Armadillo-400 Series are Class A Information Technology Equipment[3] as
defined under VCCI Council standards. There are cases where this type of equip-
ment can cause electromagnetic interference when used in home environments. In
this situation, the user may be required to take appropriate measures to alleviate the
problem.
The Armadillo-440 LCD Model (Armadillo-440 together with the Armadillo-400
Series LCD Expansion Board fixed on an acrylic board) does not meet the VCCI
standard and can cause electromagnetic interference.
In order to clear Class A when using the Armadillo-400 Series LCD Expansion
Board included in the Armadillo-440 LCD Model, it is necessary to strengthen the
ground of the expansion board. For example, by using a metal instead of acrylic
board or connecting the fixing holes of the Armadillo-440 and the LCD Expansion
Board with a wide conducting line.
Please be aware of the following points when newly designing an expansion board which connects to the LCD interface
on Armadillo-440 or Armadillo-460.
Withanexpansionboardthatincludesadevicethathaslargepowerusefluctuations,
such as with an audio amp, when only the GND line of the flexible flat cable (FCC)
is connected the expansion board may produce electromagnetic noise. To mitigate
the noise, strengthening of the expansion board's ground is recommended. For ex-
ample, by connecting the fixing holes of the Armadillo-440 or Armadillo-460 and
the expansion board GND by metal plate or wide conducting line.

3.3.1. microSD Insertion
CON1 is a hinge type connector. The cover on the connector must be opened in order to insert and remove the card. When
opening, the cover should first be unlocked by sliding the upper part of the connector horizontally in the direction shown
by the OPEN arrow.
Figure 3.3. microSD Insertion Diagram
Please be aware that the connector may be damaged if excessive force is applied.
3.4. Jumper Pin Configuration
There will be no need to change jumper pins other than JP2 in this document. Please leave JP1 in an open state. It will
be noted when any change to JP2 is required. Set it to an open state now.
The position of the jumper pins can be seen in Figure 3.1, “Layout Diagram”.
3.5. Serial Console Software Configuration
Start the serial console program and configure the connection as shown in Table 3.1, “Serial Communication Configu-
ration”. Also, please keep the width of the serial communication software to more than 80 characters. The display may
become disordered when entering commands if the width is less than 80 characters.
