Chapter 1: Product Overview
1.1 Introduction
The EDM6070AR-01 is an ARM based Single Board Computer (SBC),
designed & developed by element14. It comprises of a 7” LCD display and
touch screen assembly, integrated with multi-functional embedded
hardware based on Atmel’s ARM9 AT91SAM9X35 industrial processor.
The EDM6070AR-01 is a fully integrated Embedded Display Module solution
for a variety of embedded control HMI applications, ready to drop into your
product with negligible integration effort, OR to just wrap an enclosure
around, add a software application and become your finished product.
The EDM6070 is designed to fulfil the different requirements of various HMI
applications including:
Industrial control terminals
Intelligent instruments
Data acquisition and analysis
Medical products
Network terminals.
The EDM6070AR-01 consists of three parts: a MINI6935 CPU core module,
an expansion board, and a 7” TFT LCD (800×480) with resistive touch
screen.
MINI6935 CPU module is an ARM embedded board,
integrated with the ATMEL ARM926EJ-S-based processor
AT91SAM9X35, operating at 400MHz frequency. The board has
128MB DDR2 SDRAM, 256MB NAND Flash, 4MB DataFlash, 4KB
Two-wire EEPROM.

The Base Board expands the rich set of connectivity and user
interface peripherals of the Atmel AT91SAM9X35 including Ethernet
and CAN interface. The board also has a TFT touch screen LCD
interface, USB hosts/device, Buzzer, RS232, RS485, Audio, GPIOs
and an SD card interface to allow for large storage capabilities.
LCD Touch screen Display is a 4-wire resistive touch screen
TFT LCD display with a display resolution of up to 800x480 with
24-bit colour depth.
The EDM6070AR-01 includes Linux BSP and supports the Linux QT GUI
(Graphical User Interface) and multiple file systems like, FAT, NTFS etc. It is
also supplied with a Smart Home demo application (include smart-led
controller, weather controller, video) and a number of example applications
to give you a quick and easy start.
