- 大きな変更をするときはブランチを絶対に別途作成しましょう - 小さな変更(スペルミスやコメント修正程度)ならどんどんmainブランチに突っ込んでもまあ構わないでしょう - 余裕があったら変更した内容をコメントしてくれると助かります
- 各プロジェクトフォルダの命名規則は「hogehoge(プロジェクト名)-teensy40(開発環境名)」となっていますが、一部試験用に作ったものに関しては、この命名規則が守られておりません...ごめんなさい。 - プロジェクトフォルダ内の「src」フォルダ内にmain.cpp(一部プロジェクトは名称が異なります)、「lib」フォルダ内に各種ライブラリ、「include」フォルダ内にサブプログラムが入っています。 - 一部PlatformIOからダウンロードしているライブラリが含まれているため、基本は「VSCode + PlatformIO」の組み合わせでご覧ください。

Integrated Power Board: common questions
What microcontroller does the Integrated Power Board use?
The Integrated Power Board is built around the ATtiny85-20PU, from the AVR/Arduino family.
How big is the Integrated Power Board?
The Integrated Power Board measures 56 × 53.2 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Integrated Power Board?
25 components, from 17 distinct parts. The full bill of materials is listed on this page.
Where can I download the Integrated Power Board design files?
From the MUNAKATA-EPC/Hercules_2022 repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Integrated Power Board design in my own project?
Yes, under the terms of its MIT license, which MUNAKATA-EPC chose for the repository.
Can I test firmware for the Integrated Power Board without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
