Dan Christensen, I can confirm that this works. I compiled a default build with making no changes and could not set the station types to GPIO as there were no free pins listed in the PIN_FREE_LIST in defines.h. Then I modified the PIN_FREE_LIST to includes several pins and recompiled the code and now I can set the station type to GPIO and pick which PIN to use. I still need to actually connect some relays to the board, but it looks like this will work great!
