Yes, it is. AKA47 did some TB6560 drivers that are on separate boards here

So if you want to interface with Sanguinololu specifically, the AKA47 boards are a good choice. Current version of Gen7T is not quite ready for prime time. Or if you are doing your own, good luck, and let us know what you end up with and how well it works.
