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 TrueBypassRelayModule PCB?
It measures 48.9 × 26.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TrueBypassRelayModule use?
57 parts, built around the 78L05, TC4069UBP and 2SC1815-GR. 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 TrueBypassRelayModule KiCad files?
From the kanengomibako/Modules repository on GitHub, at the commit this page was made from: the board is TrueBypassRelayModuleTHD/old/TrueBypassRelayModule.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 TrueBypassRelayModule 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).
