Any one else having trouble sorting out the sps switching board options? I purchased the files from vfe and got many of the boards and was going to start assembling some of them. The circuit pcbs are pretty clear but when I started looking at the sps switching board it all gets fuzzy. In the files there is an SPS system board, a truesoft sps 15v board, a truesoft sps 18v board, a truesoft sps through hole board and a truesoft sps board. How the crap am I supposed to know which one to use for what? In the assembly documentation it has sps v2 assembly. It matches the 15v and 18v board but only shows one side but doesn't show the back side. No where else does it show what should go in those spots. A few are easy but a few would just be a guess, lol. The truesoft sps documentation shows yet another board with different parts and then there is a spreadsheet for an smd version that once again used another set of parts. I just wondered if anyone has come across any clear cut directions on what to use when and where with these? I really want to get some of these going but a the moment I am kinda throwing up my hands. I don't mind a little pic programing or smd soldering but this is a bit wonky, lol.
