Quantities are per assembled board. LCSC/JLC numbers are sourcing aids, not authorization to substitute footprint, voltage rating, tolerance, dielectric, or RF behavior.

Historical revision 1.0.3 corrected two supplier-code errors: C25895 selected 44.2 kΩ, not 1.18 kΩ; C412030 selected a 4.7 nH 0603 inductor, not 2.8 nH 0402. The old R3 current-setting resistor is now removed with the BQ25150 redesign. Exact supplier land patterns are imported for populated passives. C412270 had only 10 pieces reported during the earlier review; stock is not reserved and must be rechecked before ordering. Do not substitute another RF inductor without checking value, Q, self-resonance, tolerance and footprint.

This Markdown table is not a JLCPCB assembly CSV. `bun run export:manufacturing-review` now uses the released BOM/PnP exporters to exclude C23/C24 and TP1–TP6 while preserving their copper. `assembly-parts.ts` supplies these package descriptions through the official BOM resolver and rejects mismatched MPN/supplier pairs. Both generated files contain exactly 50 fitted rows. Supplier-specific rotation and centroid review remains outstanding; use the generated review manifest, not the obsolete bundled CLI export.

Not included: single-cell protected 100–200 mAh LiPo with 10 kΩ NTC and keyed JST-SH harness; 64×32 I²C OLED module/harness; SWD pogo fixture; enclosure.
