From the project

KiCad 風の基板設計アプリを、fuide (egui 0.36 向けの FUI 部品ライブラリ) の上に作るプロジェクト。今は 試作 (spike) の段階で、「Rust で使えるカーネルの調査」(docs/kernel-research.md) の結論を実際に組んで確かめたもの。

fuide 本体と 3D ビューポート fuide-3d は git 依存 (private なので SSH。Cargo.toml の [workspace.dependencies]、egui の版を揃えること)。隣の checkout ../fuide / ../fuide-3d で直しながら動かすときは Cargo.toml 末尾のコメントの [patch] を外す。

ANSI 75 PERCENT design files

The KiCad project lives in the kobago/fuide-eda repository on GitHub; these links point at the commit this page was built from.

ANSI 75 PERCENT: common questions

What microcontroller does the ANSI 75 PERCENT use?

The ANSI 75 PERCENT is built around the Pico, from the RP2040/RP2350 family.

How big is the ANSI 75 PERCENT PCB?

The ANSI 75 PERCENT measures 312 × 146 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ANSI 75 PERCENT?

170 components, from 87 distinct parts. The full bill of materials is listed on this page.

Where can I download the ANSI 75 PERCENT design files?

From the kobago/fuide-eda repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ANSI 75 PERCENT design in my own project?

The repository has no license, so all rights stay with kobago. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ANSI 75 PERCENT without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
