I found that manual in the trochotron site, googling for any kind of info on these products. I agree that it would be very helpful if they created a version with a similar scope for the current version. Arduino is very much of a DIY experience, and there isn’t a lot of hand-holding for newbies, though some of it may be indicative of the number of people using this product - I would say not a lot.
I have posted a few problems that I am looking for help with and also have received no answers.
