Prototype in manufacture includes a number of quality and functional revisions, including upgraded trace width to handle up to 3A in places where it's needed. Will be load testing and thermal testing this prototype within the next 2 weeks.

The eFuse is a new addition as are a number of mosfets, the comparator and a supervisor chip.
