• Kept the active Path B implementation on IC2, U8, U9, U10, U11, U12, U13, U15, J3, MK2, BZ1, D2, and Q2, and marked the duplicate older set excluded from BOM/PCB.
• Created named power and interface nets for the active subsystems, including USB_5V, SYS, VBAT, 3V3, MIC_1V8, VIN5V, USB D+/D-, e-ink SPI/control, charge-status, battery-sense, buzzer, RGB LED, and boost enable paths.
• Added explicit reserved interface boundaries for the unavailable T5838 and CI1302 using the existing support parts and named placeholder nets, and updated the project description to document the reserved 1.8 V and VIN5V domains.
• Ran review checks and confirmed no single-pin-net or undriven-net ERC issues in the checked categories.

• ✅ Active available library parts are integrated into the schematic with named power and control networks.
• ✅ Dedicated reserved boundaries exist for the T5838 1.8 V path and the CI1302 VIN5V analog voice path.
• ✅ Project documentation was updated to describe the reserved integration areas.
• ❌ I could not finish a clean handoff-quality schematic because some placeholder/debug nets were unintentionally merged through shared test points, so the reserved block separation is not yet as explicit and minimal-rework-safe as required.

Import KiCAD Parts

Import KiCAD-formatted components and libraries. We currently support KiCAD v4 and v5 with ".lib" extensions. We've created a full tutorial on Importing Components from Other EDA Tools to Flux if you need more information.
