KiCad Auto Builder (회로도 자동 생성)

YAML 설정 파일로 KiCad 회로도를 자동 생성합니다.

Quickstart

bash
# 1. 설정 검증
python -m kicad_auto_builder.cli validate kicad_auto_builder/examples/fcboard_power.yaml

# 2. 빌드 실행
python -m kicad_auto_builder.cli build kicad_auto_builder/examples/fcboard_power.yaml

# 3. 출력 확인
# out/fcboard_power/
#   ├── fcBoard_Power_Auto.kicad_sch
#   ├── lib/custom.kicad_sym
#   ├── lib/custom.pretty/
#   ├── bom_jlc.csv
#   └── report.md

YAML 예제

Questions

What parts does the FcBoard use?

45 parts, built around the MAX485ESA, RTL8211F-CG, USB3320C-EZK and LM2596S-ADJ. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the FcBoard KiCad files?

From the raonslab2/fcBoardKicad repository on GitHub, at the commit this page was made from: the board is backups/20251215_010404/fcBoard.kicad_pcb and its schematic backups/20251215_010404/fcBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the FcBoard design in my own project?

Its repository states no licence, so its author keeps all rights: ask raonslab2 before reusing the design.
