Me Here	9792729be0	PM_K-1 hardware: note locally-saved EVM/reference layouts in LAYOUT_REFERENCES.md ... Downloaded the 3 priority reference layouts into hardware/datasheets/ (git-ignored): - TPS65131EVM_SLVUAW7.pdf (switcher EVM 4-layer plots + BOM) - TPS7A30-49EVM_SLVU405.pdf (+/-15V dual-LDO EVM, schematic+layout+BOM) - RP2350-Minimal-KiCAD.zip (official RP2350 KiCad: nested RP2350A/QFN-60 + RP2350B/QFN-80) Verified the switcher EVM contains the full Top/Inner1/Inner2/Bottom layer plots.

Me Here	795252fbce	PM_K-1 hardware: LAYOUT_REFERENCES.md -- manufacturer reference layouts per stage ... Maps each stage to its authoritative layout reference (EVM / datasheet layout section / app-note / reference design) with URLs + the key takeaway, to complement LAYOUT.md's general rules. Standouts that match our exact circuit: - TPS65131EVM-839 (SLVUAW7) -- switcher layout to copy - TPS7A30-49EVM-567 -- a +/-15V dual-LDO EVM = our exact rails - RP2350 Minimal-KiCAD.zip -- official MCU/USB/crystal/QSPI reference layout (+ footprints) Plus PCM5102A community refs, THAT1646/1240 reference boards, TI op-amp layout app-notes (SBOA092B/SLOA046), RV-8803 app manual solder-pad section, USB-C/USBLC6 diff-pair rules, and TI class-D layout for the PAM8302.
