After we sent out the survey, we only received some responses. Too few to start the production. But the people that did respond are really hoping to see the case come into production, and so do I (I own one Micro USB board). At the same time, I realized that we don’t have to manufacture the whole case - we can reduce the risk by only manufacturing the bottom part of the case, cause the top case is compatible with the existing Type-A version.
So we have decided to offer 10 Micro USB version cases at the same price as the Type-A version. To make it simple, all 10 cases would be Tetra version (all on-board RF and CLK lines to be externally available).
Here what it will look like:
