# A0 bill of materials

**Untested prototype — schematic reviewed; routed fabrication validation pending.** 85 fitted electronic components. Each row maps to official JLC assembly catalog evidence with individual UTC check dates, stored in references/catalog. Availability is a dated snapshot, not a reservation. Through-hole terminals use manualWeld: confirm Standard PCBA/manual insertion eligibility at quote review.

CSV follows [JLC's BOM field guidance](https://jlcpcb.com/help/article/bill-of-materials-for-pcb-assembly), with extra audit columns. No CPL/assembly upload has been approved.
