歡迎來到成大 ISP 航電組的協作平台！這裡存放了我們為比賽設計的所有電路圖、PCB 檔案以及相關硬體參考資料。
為了方便大家協作、快速找到規格書，我們對專案資料夾進行了全面整合與邏輯分類。請大家開發前務必詳細閱讀以下指南。
我們採用結構化、模組化的資料夾配置。請在您負責的子專案資料夾內開發，並參考對應的規格書：
教學/教學624.md：最新完整版開發教學（三角色架構、板間鏈路與不對稱備援、雙鏈路遙測協定、地面站、主機端測試）。 PROJECTHISTORY.md：專案演進史，記錄重大決策與轉折的「為什麼」。 docs/：工程／規劃文件索引（硬體規格表、改進計劃、進度、設計筆記、需求驗證、測試方法）。
為了避免「悲劇」（檔案衝突或覆蓋），每次開工前請牢記口訣：「先拉，再做，後推」。
為什麼？** 這能把雲端最新的進度同步到你的電腦。如果不拉就改，上傳時會發生嚴重冲突。

Power layer: common questions
How big is the Power layer PCB?
The Power layer measures 68 × 68 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Power layer?
47 components, from 26 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Power layer design files?
From the rayho6240-arch/RocketCup-avionic-board-project repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Power layer design in my own project?
The repository has no license, so all rights stay with rayho6240-arch. Use it as a reference, and ask the author before reusing the design.
