Standalone ESP2 development board?

So, I'm starting to think that I should create a new PCB for the ESP2 so that I can play around with effects algorithms. If I can get things to work directly on the ESP2, then I think I'll have a better chance of figuring out the entire EDS card.
If I were to make a board, what form factor should I use though? Should I make a standalone unit like the Freescale Symphony Soundbite that has audio inputs and outputs on one PCB or should I create some kind of daughter card that would plug into something like a Beaglebone Black, Raspberry Pi, or something similar?
Anybody else twisted enough to want to work with me on something like this?]]>Doug Wellington2014-02-14T18:33:12-00:00Re: Standalone ESP2 development board?

If I get a chance this weekend, I'll look at the various bus specifications to see if I can leverage one of the designs from the Papilio, the Mojo, or the BBB. The Ensoniq stuff uses the I2S protocol, but most of the recent stuff I've used is SPI-based. Worst case, I'll find some kind of converter or use a CPLD or small FPGA to make one...]]>Doug Wellington2014-02-14T20:48:53-00:00Re: Standalone ESP2 development board?

Some of these have SP/DIF, USB, more memory, on board graphic processors etc. I also saw models with wireless keyboards that had a track pad and joy stick. You might want to do a search for quad core android TV box. I'm not sure what guts or DSPs they have inside of them... I know you are talking about DSP, so this may be the wrong track, but I thought I'd mention it.
