Changes

* The data bus was split into two, and the number of pins broken out was reduced only to the number of GPIOs free after all avionics systems, simplifying routing and reducing the number of pins.

* Abandoning an embedded RockBlock, which required dedicated power circuitry and a very large footprint which required incredibly dense packing and clever routing to accommodate the rest of the system

* Removing some current sensors, because power consumption data for its own sake is not considered a priority for standard-profile launches
