Open smartphone
The reuse extreme. Almost every line is commodity silicon — so the cost lives in integration, not design.
A phone is where reuse maxes out. Pine64 publishes the schematics; nearly every part is a settled, sealed module. If the goal is to ship a phone, that is the point — the cost is integration, not design. If the goal is to compete on the platform, the descent shows the few places differentiation is even available.

Decompose the product into its stack. Each layer is colour-coded: settled, cyclical, or frontier.
Bill of materials
Every part is a real, sourced component from the open baseline — no invented part numbers.

A smartphone is near-total reuse: eight of these nine lines are commodity silicon, and the cellular modem is a sealed, pre-certified module. If the goal is to ship a phone, that reuse is the point — this is assembly, and the cost lives in integration, not design. If the goal is to compete on the platform, the energy island is where differentiation is available: fold the PMIC together with an always-on neuromorphic sensor hub so the application cores can sleep through wake-word, motion, and context — at custom-silicon cost. The system shows where each option sits on cost versus differentiation; the goal is yours to set.
