POWER-SUPPLY RECOMMENDATIONS
Make optimizations in the power supply section to reduce the number of individual rails and filters to save on BOM and space. One possible
optimization is the combination of different rails of the same voltage domain. In doing this, it is important to identify the aggressor and victim
rails to decide what to combine and what to keep shielded with an FB filter.

For this experiment, the combined rails are as follows. This reduces the number of caps and ferrite beads needed on the board.
