PCB Import Help
Worked for 8 mins 16 sec
The schematic BOM is now in Flux with 53 components added and source metadata preserved. I’m moving to connectivity next, starting with rails, USB-C, SD card, CAN, buttons, and LED nets.

Reconstruction is in Flux: I added the YachtWave Rev B schematic BOM, recreated the major power/USB/SD/CAN/LED/switch nets, marked unused ESP32/USB-C pins as no-connect, and saved details in KiCad Schematic Reconstruction Report.
Open items:
- ERC still has 9 floating-pin warnings in the power-input/filter/jumper area:
C13,C5,FL1,L1,JP1, andR10. - A few exact parts were unavailable, so closest library alternatives were used and flagged in the report.
Suggested next steps:
- Do one focused cleanup pass on the remaining 9 floating pins.
- Assign Flux-native footprints/packages to generic passives.
- Visually organize the schematic into readable functional blocks.
- Rebuild PCB placement/layout from the KiCad PCB reference.

The Flux schematic has been rebuilt from the uploaded KiCad schematic source with the major BOM and logical nets recreated.

Library substitutions / non-exact matches
The following source parts were not available as exact Flux library parts, so closest usable parts were inserted and the original source metadata was preserved in component properties:
Table
| Designator | Source part | Flux part used | Notes |
|---|---|---|---|
| D7, D9 | XINGLIGHT XL-3216UGC-FB, LCSC C3646937 | XL-3216UGC | Same green 1206 family, but not confirmed reverse-mount -FB variant. |
| D8 | Amicc A-SP1513R6GHB1C-A012A, LCSC C5355463 | MHT151RGBCT | Similar 4-pin RGB LED/pinout family, not exact manufacturer/MPN. |
| F1 | Source 1A 1206 fuse, LCSC C52988549 | 1206L100/33NR | 1A 1206 resettable fuse alternative; exact source LCSC part unavailable. |
| FL2 | TDK ACT45B-510-2P-TL003, LCSC C76584 | ACT45C-510-2P-TL000 | Closest 510-series 4-pin common-mode choke found, but not exact ACT45B MPN. |
| U2 | AP63203QWU, LCSC C5248536 | AP63203WU-7 | Same AP63203 fixed 3.3V function/pin count; suffix differs. |
| U4 | MCP2562FDT-E/SN | MCP2562-E-SN | MCP2562-compatible SOIC-8 CAN transceiver library part. |
Verification status
Electrical checks were run after reconstruction. Remaining warnings are limited to a small set of pins/nodes that still need confirmation from the original KiCad geometry or follow-up cleanup:
C13:P1C5:P1FL1:2,FL1:3,FL1:4L1:2JP1:A,JP1:BR10:P1
Unused ESP32 GPIO/UART pins and USB-C SBU pins were intentionally marked no-connect.
Important caveats
- This is a schematic reconstruction from the KiCad text file, not a native KiCad project import.
- PCB placement/routing from the KiCad PCB was not imported.
- Several exact footprint/package assignments on generic passives were preserved as KiCad metadata, but should be mapped to Flux footprint/package properties before layout.
- The remaining floating pins are mostly in the power-input/common-mode/filter/jumper area and should be resolved by one more focused pass against the original KiCad file or by importing/viewing the source schematic image.
