Not many units was produced, this was a beta production, to assure that everithing go well with industrial production, since until now only hand soldered prototypes was done of all the revision from v.1.0 to v.1.3.
After a functional test, since MTM (Mizar32 Test Machine) is not ready yet, it seems that the quality is very good, without defective unit.
To shop the boards pls wait for second batch that will come soon this end of September.
