Hi Richard, The current version won't support more tubes. I will do a 15 or 16 tube version, but I'm not sure when it will be available, but probably by the summer. I haven't started working on the hardware or software yet.
The B7971 version will be available by the end of this month, and the two digit add-on board, probably a month or two later.
