Overview
Flow is an open-source printed circuit board by TakaI2, from the TakaI2/Drone_simulate repository on GitHub. It is a 2-layer board of 30 × 24 mm with 14 parts on 11 nets, routed with 223 tracks and 80 vias.
It is built around the PMW3901MB-TXQT, VL53L1CXV0FY/1 and XC6206P182MR-G, with the SM08B-SRSS-TB(LF)(SN) among its other parts. Its parts include 6 capacitors, 3 ICs, 2 resistors and 1 connector.

README
README.mdDrone Design Studio
固定ピッチの多ロータ機（ドローン）を、飛行シミュレーション → 推進系・電気設計 → 基板の自動配置配線 → 機体設計 → 統合検証まで一貫して設計するツールです。ブラウザだけで動きます。
- 屋内（オプティカルフロー）・屋外（GNSS、風、自動帰還）・都市（横浜みなとみらい、PLATEAU の建物）の飛行シミュレーション
- 推進系の探索、回路生成と電気計算、2 層基板の自動配置・配線、Gerber / KiCad 出力
- 3D プリント用フレームの生成（重心・強度・隙間の検証、STL 出力）
- 3 つの設計例（版 A：1S ブラシ付き、版 B：センサ子基板＋GNSS 端子、版 C：屋外用ブラシレス）と予算
使い方は docs/manual.md、設計の経緯と検証結果は reports/index.html を参照してください。
開発
npm install
npm run dev # http://localhost:5173
npm test
npm run build # dist/ にサイト一式（アプリ＋out/・reports/・docs/、マニュアルの HTML 版）公開（Netlify）
netlify.toml に設定済みです（ビルド npm run build、公開ディレクトリ dist）。Netlify で GitHub リポジトリを連携すると、push のたびに自動で公開されます。設計データ（out/）とレポートはリポジトリに含めたものを公開するので、設計を変えたら各スクリプト（npm run all など）を実行してから push してください。
注意
結果はシミュレーションと計算上の値で、実機の安全性・性能・飛行の可否を保証しません。飛行は法令・条例に従ってください（詳しくは notice.html）。

Questions
How big is the Flow PCB?
It measures 30 × 24 mm and has 2 copper layers, 0.8 mm thick.
What parts does the Flow use?
14 parts, built around the PMW3901MB-TXQT, VL53L1CXV0FY/1, XC6206P182MR-G and SM08B-SRSS-TB(LF)(SN). 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 Flow KiCad files?
From the TakaI2/Drone_simulate repository on GitHub, at the commit this page was made from: the board is out/variantB/flow.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Flow design in my own project?
Its repository states no licence, so its author keeps all rights: ask TakaI2 before reusing the design.
