README
10VBlocker/README.md10V Blocker
10V以上の電圧が入力されると、電源供給を遮断するモジュールです。
配線方法
- IN → 電源入力 +
- 上側中央のパッド → 電源入出力 -（グラウンド）
- OUT → 電源出力 +
基板下側のパッドはどこにも接続されていません。マル信無線電機 DCジャック MJ-40Aに直付けする場合、電池の接続が可能です。
注意事項
- 新品の電池は電圧が10V以上の場合があり、本モジュールにより電源が遮断される可能性があります。
- 電源の遮断が不十分となる場合があるため、消費電流0.1mA未満の機器には使用しないでください。

Questions
How big is the TrueBypassRelayModuleMicro PCB?
It measures 17.9 × 15 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TrueBypassRelayModuleMicro use?
19 parts, built around the ATTINY202-SSN, 78L05 and 1N4148WT. 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 TrueBypassRelayModuleMicro KiCad files?
From the kanengomibako/Modules repository on GitHub, at the commit this page was made from: the board is TrueBypassRelayModuleMicro/KiCad8/TrueBypassRelayModuleMicro.kicad_pcb and its schematic 10VBlocker/10VBlocker_RevB.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TrueBypassRelayModuleMicro design in my own project?
Its repository publishes it under the Unlicense licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
