Версия 16.2.8b от 1.11.2025
Версия, основанная на v16.2.8a мигрированная из EasyEDA в KiCADv9.0.
Есть некоторые изменения и дополнения, связанные с более жесткими правилами валидации схемы и платы в KiCAD. По идее, должно стать лучше :)

Questions
How big is the Scorpion-256-Turbo PCB?
It measures 214.6 × 162.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Scorpion-256-Turbo use?
733 parts, built around the 1N4736A. 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 Scorpion-256-Turbo KiCad files?
From the romychs/Scorpion256TPlus repository on GitHub, at the commit this page was made from: the board is KiCAD/Scorpion-256-Turbo.kicad_pcb and its schematic KiCAD/Scorpion-256-Turbo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Scorpion-256-Turbo design in my own project?
Its repository states no licence, so its author keeps all rights: ask romychs before reusing the design.
