Bill of Materials — V9

Values Are Not Reliable

This is the V9 as-ordered BOM. The Comment/Value field is not reliable — voltage ratings and other details may be incorrect. Multiple components share the same LCSC part number regardless of the voltage rating shown in the Comment column. Do not use this page as a design reference without cross-checking against the verified as-built review.

For verified component ratings, see the individual hardware documentation pages.

Doc audit 2026-05-23

The individual hardware pages were cross-checked against the V9 schematic netlist on 2026-05-23. The audit corrected several stale designators (HCPL2531 listed as U3 — correct designator is U13; HCPL2531 output pull-up listed as R65 — correct is R63; ADS1115 footnote LCSC; INA228 D20/D21 ESD diodes that don't exist; nmea2k.md MPM3610 mislabeled as MCP3610AGQV and incorrectly called isolated). Field-level pin numbers and divider math were also re-derived from datasheets where present (LMR36510, MPM3610, TLV62569, INA228). Where this doc and an individual hardware page disagree, the individual page is authoritative.
