My ARM9 Development board for indian developers

The Low Cost ARM9 board is here .


I always wanted to bring a low cost solution for indian developers .
A highly capable ARM9 board that can run embedded realtime linux .
with ample amount of memory and provision for future expansion.

Now! Why to pay 40 k for an ARM lab setup with JTAG and all ...my design is just <6K Rs.

The design criteria is fulfilled with AT91RM series ARM9
chip based design . Added 256MB sdRAM,64MB flash,24LC512 eeprom,
can, JTAG , USB serial interface( for laptops this is handy as there is no serial port ), CAN bus transiever, controller . It has a USB host too! there are more interfaces can be added .



There are many online ported versions of linux for the chips as well as develeoper forums /Groups .


Designed during off time and now almost ready :
See the snaps of it :






After working 4 years in embedded product domain , i felt the need of hardware test setup for learning board level porting, device drivers BSP development.
As well as a board that is suitable for my Oscilloscope needs.In the company where I work as consultant need for linux low cost setup was apparent, i got approval to initiate the project for internal usage . Company is willing to go open source for the design, time to materialize the concept!


Possible uses :
> It is full linux development lab ,you can test the device drivers ,Realtime programming, hardware interface,data acquisition, audio interface ...what ever you can imagine.

>a full featured oscilloscope , there are card designs freely available
on net for the input section , write the code + add a graphic LCD .. this is
your storege oscilloscope ... do all the tests you like E.g . View Pulse shape,


>Industrial acquisition system ,security system , embedded webserver,
CNC controller ... remote controller ,touch screen kiosk.
>Torrent downloader with open Wrt ported

There is linux OS on the board so you program as you like . The PCBs will be coming soon . Will update here.
