Quick visual guide to create your own board

Click on the following image to take to see how it's simple to wire external components to design your custom board using CORE9G45.

Evaluation boards and fast prototyping systems

A full features and easily expandable CORE9G25-CON board is available to evaluate the CORE9G25 SoM or to create end-user products for prototyping or low volume productions in the following application fields:

Evaluation Board Feature Expand the 7 USART serial port on TTL Level Expand 100M Ethernet Expand Two USB Host Expand SD card slot Power supply input: 9-28V Size: 13cmx13cm EmDebian 7.1 Wheezy with Linux 3.10 available Buildroot Filesystem support   Provide the Evalution Board schematic and PCB file in PADS.

Software environment and development tools

CORE9G25 can support Linux&Buildroot and Linux&Debian system, The two linux distribution have different function, the customer can choose one to use it.

Linux&Buildroot:

• Buildroot is a configurable Makefile which downloads, configures, and builds cross compilers, the kernel, busybox, and most of the other stuff needed for a simple, small complete Linux distribution and root filesystem based on uClibc, glibc or EGLIBC C libraries
• Small root filesystem, you can install the system in Nand Flash
• You can refer to it in the atmel website: http://www.linux4sam.com
• We provide the source code and system image in CD. 
• Provide the developer method manul in the CD
• Support SSH, DHCP

Linux&Debian:

• big root filesystem that contain more function, you have to install the system in SD card.
• It is possible to develop in almost any language using differents tools. In the developers page we illustrate some different development methods available and examples to manage the embedded peripherals in C or Python languages.
• The C compiler and the Python interpreter are pre-installed by default. Also a small web server (Lighttpd) and PHP language interpreter is already available for the web development.
• Visit the developers index page...
• Other languages, tools, web servers, etc are available from Debian binary repositories and can be installed in few minutes.
• We propose, by default, a Debian Linux bootable from SD card. Ready to use SD cards are available on our eShop but any executable can be built starting from sources and following our tutorials. The basic requirements are a Linux Ubuntu PC.

What you have to know before buying CORE9G25 SoM

Price

The CORE9G25 prices are fixed so don't change for hi-volume batch, the follow is the quantity price:

These are the main reasons:

• CORE9G25 is a Made in China product and you can buy directly it from the China factory so no resellers charges are applied to the final cost
• Since it is made in-site we can apply the same discount for one or 1K boards because in every case we have to make the board one by one and we have access to hi-volume prices from our provider for components used on it
• Each order is paid for in advance so you don't have to pay any interest rates
• You can buy the CORE9G45 on-line using our eShop or by contacting directly us. We can speak English.

Warranty terms

We make deep functionality tests on any outcoming board and the warranty does not cover boards which have been left out of its original enclosure for a long time (max 10 days) or when the pads are welded (please read the terms and conditions for more details).

Incoming test equipment

If you need to do an incoming quality test before mount the boards, we can provide a copy of our functionality test equipment we using for our outcoming tests contact us for more info and pricing.

Custom boards based on CORE9G25

If you like CORE9G25 but have no time (or skill) to design and produce an OEM device by yourself, please Contact US(support@armdevs.com), we could help you to create your custom project.
