I was one of the early assemblers of the kits that Andy sent out. Since I'm using step/dir for it there were some firmware bug updates happening and one really great upgrade that makes it easier in the long run to update firmware on both boards.
The STMBL is not targeted with step/dir as the primary control so the interface is RS485 for each of the step,dir and enable signals. I had to breadboard up a small level translation module to deal with that. Apparently it's possible to use one of the other headers with I believe 3.3V logic but I really didn't like that idea. I would have preferred optical isolated inputs. But otherwise, the motor behaved as expected using my ELS as a step/dir generator. Even with the little grumbles I can honestly say I really like the STMBL. And the support from Rene's group and from Andy has been terrific. So would I suggest it as a usable drive? Yes. Is it possible to get one with that output current? Not sure the driver chip was discontinued and I know they are working on a Rev 2 but I don't know when that will happen.
