This change is a hardware bump, with minor firmware changes:
Improve the Japanese language text (thanks to Vis Virial for the pull request)
New batch certificate (#2) for first build of version 3.0 hardware.
Look for version “2.2.0” in the firware with checksum: 753ec10262f92c6bbe4f9a01e440278c36c2c8352ed897a75aabb0993d63ab9a and complete version string: 2.2.0.20170721.115213
The real news is on the hardware side, where we made a number of changes to improve reliability and manufacturability:
The device is now 47mm long, up from 40mm. The extra length solves an issue we saw with some USB ports that didn’t allow proper and complete insertion.
Protective plastic is now applied into a narrowed section of the board, which better secures it, makes the product look more “finished”, and generally should improve the quality and appearance of the product.
We moved the “unseal” hole a little further under the plastic, just in case.
The edge of the board will be more smooth with less rough spots due to changes to how we make the PCB.
Board is marked in gold with “v3.0” and “r.A” (for revision A).
