Hi Antti,

SoundBite board was designed to be as low-cost possible due to University
support program requests.

The board is $150.00 USD I believe, we thought about a version that used the
DSP56720 with pads to add more memory and use better analog audio
connections. Management pulled our plug and said to put our efforts onto
some ARM based projects which we did.

Still, I wanted to build the DSPB56720 platform but I wonder what folks
would be willing to pay for a bigger / better platform?

I can do the design in Eagle easily enough and get some boards built and
sell blank PCB and assembled goods.

Some feedback on connectors would be nice as well as possibly adding a MCU
vs SPC/I2C header.

We have a good deal of tools that support this part and it would be great to
see some inputs on a next spin platform.
