The number of unique parts in a design defines the complexity and human intervention during assembly.
Steps to reproduce
Refer to the bill of materials and parts list
Count the number of unique SMT parts
Expected result
Any parts more than a mid fourty quantity threshhold are considered of urgent need.
Actual result
Several parts in the bill of materials could possibly be reduced by equivalent substitution.
Severity level
This is low priority because project requirements do not mandate in house assembly.

Consolidate R9 pullup from 100K to 10K, R11 and R12 pullups from 3K9 to 10K, R13 pullup from 1K to 10K, and R14 and R15 pullups from 4K7 to 10K. This reduces unique parts by four.
Consider consolidating all load capacitors of both crystals C18, C19, C95, and C96 to the same value, such as 12pF or 15pF. This would reduce unique parts by one.
Consider (ask the reference design publishers) consolidating FB1 at 120Ω and FB2 at 470Ω, to reduce unique parts by one.
