I just went looking for these myself and it appears that they're not there even now.
Its mainly the CV module i'm interested in. In my head I thought going from a 0v-5v littlebits signal to a signal I can route into a eurorack compatible module would be quite straight forward. But the synth pro CV module I own looks like its got a lot of stuff happening on the underbelly. It even appears to be re-programmable via some pin pads. So that shows how little I know about this kind of thing, and without the schematics I suppose I'll remain clueless.
