Hi,
This is a very good idea to get developers opinion before you design
a development board.

I think LPC2888 BGA board will not be that low cost as Olimex
offers. So why not make a sophisticated but comparatively low cost
(within 250$ with a cheap debugger would be reasonable) system!

I would like to suggest you to design a board with FPGA. You know
very well it is being very useful in the system. LPC2888 with a
comparatively low cost but with high performance FPGA would be
great. It will make your board unique and something different from
others.

If you want to develop an ordinary development board then i would
prefer-

1. One think is very clear. That is - this MCU application is very
much related to the audio based system development. At least I2S,
high speed USB2.0, 16-bit sigma-delta ADC tell so. Philips most
probably wants to compete with "Analog Device" in this part. So,
audio input output ports are obvious.

2. I use Phytec phycore-LPC2294 where they implemented sub-module
SBC. I think that design is very suitable. It would be better if you
design a board with that type of sub module system.

3. One very important thing in LPC2888 is that- it has high speed
USB 2.0 transceiver on-chip. So, take care of this feature. Better
to use normal USB port instead of mini USB port.

4. More external on board flash memory and RAM is preferable. Also
slot for at least SD memory. More memory interface to get use of
USB2.0 high speed :-)

5. I didn't see any integrated sigma-delta ADC in MCU before. So
more I/O ports are obvious fora  good design with LPC2888.
6. I think network connection has a great role on a development board while
most of the cheap boards fail to implement. Why not add a 10/100 Mbit/s
Ethernet on board!

To be precise if you make use of high speed USB2.0, more memory
interface(at least SD memory) , on board RAM and memory , and audio
I/O then it would be a great and unique design.

I will look forward for reply regarding my concepts.

Thanks a lot.
