So if you look in the eagle files in the universal documents folder it has all the switchboards I listed. the picture in the assembly folder shows Truesoft sps v3.1 and has a few smd on the back and th on the front. If you pull up the eagle file it's actually version 3.2 and has everything on the front and is all through hole. I assume this is the one I will eventually use. In the eagle files there is also an sps 15v (shows sps v3) and an sps 18v board (shows sps v3.4). The 18v appears to be the newest based on date. I also looks like it has fewer components and returns to the th on the front with a few smd on the back. In the assembly file it shows sps v2 assembly which matches the 18v and 15v format but doesn't show anything about the smd components on the back. Essentially there is nothing in the assembly folder that matches any of the actual boards completely.
