BOM for JLCPCB assembly

Status: v1.0, 2026-10-24. Production files in hardware/jlcpcb/: rp569-gerbers.zip (board), rp569-bom.csv (BOM) and rp569-cpl.csv (placement, from the routed board hardware/rp569-routed.kicad_pcb), written by hardware/gen/gen_fab.py (DRC gate, gerbers, drill, then gen_bom.py; build.sh also re-runs gen_bom.py). LCSC numbers live in hardware/gen/board.py (LCSC_BY_VALUE) and are copied into the LCSC and MPN fields of every symbol and footprint.

Stock, class and price come from the jlcparts snapshot of the JLCPCB catalogue dated 2026-10-23. Check stock again on the JLCPCB site when ordering.

Summary: see the table below; 2 consigned parts (CH569W, GSB343K33HR). 2026-10-24: the four HSPI 33 Ω arrays (C25501, Extended) were dropped (D-018), one Extended line and its loading fee fewer. The LM66100 pair was replaced by a TI TPS2121 (C485916, D-015). Parts cost about $15.5 per board at quantity 1, excluding the consigned parts and assembly fees.

Parts JLCPCB does not stock (consign or hand-solder)

Part	Refs	Why it stays	Options
WCH CH569W (QFN-68)	U10	The whole point of the board; JLCPCB lists no CH569/CH565	Buy from WCH/LCSC marketplace/AliExpress, send as consigned part
Amphenol GSB343K33HR	J10	Through-hole shell legs (R-16)	Consign; JLCPCB only has the SMT-shell GSB343133HR (C464578, 28 in stock)

Changes made for JLCPCB

• RGB LEDs: Cree PLCC4 footprint replaced by LiteOn LTST-C19HE1WT (C458749, 1.6×1.6 mm, common anode, KiCad footprint exists). Pinout from its datasheet: 1 = red K, 2 = green K, 3 = blue K, 4 = common anode; symbol Device:LED_RGBA has the same numbering. Its green/blue Vf is 2.8–3.9 V on a 3.3 V rail, so G/B series resistors went from 330 Ω to 100 Ω (red stays 330 Ω).
• 2.2 µH buck inductors: FTC303015D2R2MBCA had only 9 in stock → FTC303020D2R2MBCA (C7423318, same Changjiang 3×3 mm family, 2.0 mm high instead of 1.5 mm, 4.7 A).
• 3.3 µH RP2350 inductor: AOTA-B201610S3R3-101-T (C42411119), the part named in the RP2350 hardware design guide. Only 119 in stock: order early or keep an alternative (e.g. FTC201612S3R3MBCA C18724415, not yet checked against the RP2350 guide’s requirements).
• 12 MHz crystal: ABM8-272-T3 (C20625731), the RP2350 hardware design guide part (CL 10 pF, 15 pF caps).
• 30 MHz crystal: X322530MOB4SI (C70592), CL 12 pF; 15 pF load caps kept as in phantomdrive.

Before ordering

• Check every rotation in JLCPCB’s placement preview: KiCad and JLCPCB disagree for some packages (QFNs, SOT-23, connectors, LEDs).
• Pin headers are THT. JLCPCB fits them only with THT assembly; otherwise remove those lines and hand-solder.
• The CPL comes from kicad-cli pcb export pos (Y is negative, as JLCPCB expects for KiCad files).
