The board that is factory installed is not available separately, but the Micro-Tsunami fits just fine. I think the "Light Logging" version is the one you are looking for. I can't remember the speaker size off hand - I want to say the Soundtraxx 1.1" speaker, but hopefully someone else will chime in (or just measure.)
The OEM version that comes preinstalled works great, but it lacks some of the features the full Micro-Tsunami version has. Get one of those "blank" 8 pin plugs and with some quick soldering to it, you can plug it right into the Shay's DCC plug.
Hope that helps!
